Customers like the brightness of the lamp. They say it's amazing at waking them up, and it brightens very gradually and softly. The light gives a nice soft glow, and is nice for reading. Some say the light starts a deep orange and fades into a brighter white.

Customers like the appearance of the lamp. They mention it's simple, pleasing in terms of aesthetics, and well thought out. They like the color of the light and sounds, and say the warm colors really improve the mood. The lamp looks glassy, and has a very natural and gradual wake up process.

Customers are mixed about the performance of the lamp. Some mention that the buttons work well, the radio works well, and it works great as a nightlight. However, others say that it doesn't work well and seems to randomly stop working once a year. The controls are not intuitive, and the product doesn''t go particularly well with antiques.

"...In short, it's simple to use and it's effective. I've had zero issues with the stability of the device as some other reviewers alluded to." Read more

"...Its expensive, lacks intuitive controls, seems to randomly stop working once a year with no way to troubleshoot or do diagnostics...." Read more

1,081 customers mention472 positive609 negative

Customers are mixed about the readability. Some find the wake-up profile pretty easy to use, with easy controls and instructions. They also say it's likable and easy to make up in the morning with the different sound. However, others say that the ease of use is a little tricky, tedious, and confusing. They say the controls are not intuitive and the instructions are a bit confusing.

"After reading all the reviews about poor design and an extremely complicated set-up, I was a little worried about getting this..." Read more

957 customers mention573 positive384 negative

Customers are mixed about the sound quality of the lamp. Some mention that some of the sounds are better, the speaker was loud enough, and better quality sound than they had imagined. However, others say that the sound also changed to a high pitched noise that's quite unpleasant. The audio selection could be better, and there aren't a lot of sound loop options for alarms or sleep mode.

"...I use the bird chirps because they sound the most natural (and have woken me up irl before on days where I didn't set an alarm)...." Read more

"...Cons: No internet connectivity, meh sound quality, not a lot of sound loop options for alarms or especially sleep mode." Read more

"...When the alarm goes off, it starts off quiet and gradually gets louder. You can choose how loud you want the alarm to get...." Read more

"...The sound quality is good, clear, and loud enough to awaken me the first couple nights when I slept through the light, with the birds getting my cat..." Read more

738 customers mention351 positive387 negative

Customers are mixed about the value of the lamp. Some mention it's well worth its asking price, while others say it'll break easily. The price tag is difficult to swallow, and the lamp is overly cumbersome at this price point.

"...Its expensive, lacks intuitive controls, seems to randomly stop working once a year with no way to troubleshoot or do diagnostics...." Read more

"...Overall, the alarm is not cheap, but very effective for shift workers, travelers, even parents of young children who have variable schedules." Read more

688 customers mention77 positive611 negative

Customers find the buttons on the lamp to be difficult to navigate and small. They also mention that the buttons are scattered across the top of the clock and there's no button for the alarm. Overall, customers are disappointed with the buttons and controls of the product.

A Few Differences From What I Read About This Product...... See Photos~
Since this product has already been reviewed over sixteen hundred times and some quite thoroughly (thank you!), I'll keep this review short (for me). This has been one of our favorite purchases we own here from Amazon!I'll mention a few things that I think vary from what I remember reading (and I read a TON or reviews, lol) and am uploading some photos so you can get a closer look and see what I mean...First, I read some frustrations about not being able to set the time or alarms without accessing the buttons from above. I'm able to set the time and alarm times via the touch buttons on the front, below the time (see photo where buttons are lit). You can also use the upper buttons but don't have to for everything. The only thing you have to use the upper buttons for (in relation to setting alarms) is to turn an alarm off or on. For us, this isn't a daily event since we usually get up at the same times so no big deal.Second, I was under the impression from the reviews that this thing would be kind of huge but I guess that depends on what you consider large, lol. I posted a photo with it next to some small alarm clocks and a bill to give you an idea of it's size. For us, it replaces both an alarm clock and a lamp on a nightstand so it's not too large.Other than that, my wishes are few. I wish it included AM radio and didn't remember reading that it didn't (but I wasn't likely thinking I'd miss it). Sometimes I miss a little talk radio but other technology obviously suffices.Like others mention, the buttons above are out of sight from the front. Call me crazy, lol, I used a Sharpie to mark lines where the buttons are. (There's no reason for my using different colors except that I added the red lines later and that's what I had handy.) Feeling around for the buttons when you want to turn the light or radio on, off, up or down, is just annoying. When I finally buy a yellow or orange Sharpie it'll look more like sun rays, haha... And rubbing alcohol rubs it right off anyway. The last two photos show all of the upper buttons, all the way around.Lastly, the snooze sensitivity is too high for my preference. If I set down a cup of coffee near it, during the alarm time, it snoozes the radio off. I could change the settings for no snooze but I like waking up to radio and having the option of touching it for more quiet time. If I softly close a drawer below it, same thing, it snoozes.I'm generally not this generous with 5 star ratings but overall I think the good heavily outweighs the bad and I definitely love this product. We've had ours for 5 months without problems but I'll update this review if anything changes. We live in the grey Seattle area and the sunshine this thing brings us makes it the best alarm we've owned. Smile. Buy with confidence. Hope this is helpful!

Reviewed in Canada on September 10, 2016
Well maybe it helps that i'm using it either just the work week or everyday. I'll start by saying this item has a steep price especially if you have never shopped for similar products and your impression is "it's just an alarm clock", however after using this I feel it is totally worth it and I'm extremely satisfied having bought it on sale. Also it has been around a month I've had this product. Let's get in the thick of it :

Main features :
-whole wake-up light thing:
As advertised you set a time and set a sunrise time. The sunrise time is how long before your alarm goes off the product starts emulating a sunrise i.e alarm clock set at 6 am and sunrise time is 30 min : at 5:30 the sunrise starts and at 6 the alarm starts accompanied by the max brightness setting you chose. Basically, it'll start with very deep red all the way to searing of your eyes **insert spongebob patrick meme** (by which I mean this lamp gets really bright) white light with your alarm going off. You choose how bright you want it to be so you can tone down the whole searing your eyes part to satisfaction. I personally have trouble getting up and thought I might as well try this product to remedy the getting up part and it has helped immensely. It has happened to me multiple times in my past few week to wake up BEFORE my alarm goes off. I'm waking up just to the light and it feels awesome with minimal drowsiness and with a state of rest that i'm able to get up. There is no zombie like wake up part. Works for me just as advertised. Also, there is a demo mode so you can see in accelerated mode (90 seconds) the sunrise from deep red to white with the alarm sound/music of your alarm. To snooze you just touch the front part pretty much anywhere and it will snooze.

- overlooked sunset feature:
This is by far my favorite feature. You set a time between 5 and 60 minutes(available options : 0,5,10,15,20,30,45,60) for your sunset. You set the initial brightness to adjust again the whole searing eyes part. It then goes in reverse order of sunrise from white through orange then red till off. The red is really deep and I got slightly scared the 1st time it felt like my room was suddenly out of the shining or Dexter being covered in blood. The best part is it really triggers you to fall asleep. I've also a lot of trouble falling asleep and this really eases me into drowsiness without drugs regardless what I'm doing (in my case reading). Also, it helps get to bed on a more precise time. In my case I'd usually try and read to fall asleep and i'd just end up reading for hours and not falling asleep or going to sleep really late. With this, well it's time to go to sleep when there is no more light since it goes completely off (time display remains on) and I'm usually real sleepy by the end of the cycle. I honestly love this feature more then the wake-up. It give a limit on your bedtime routine and I really like that.

Other features:
The product obviously offers regular options 2 alarms, sounds or fm radio(no am if i remember correctly), 12h or 24h time display and awesome rubber feet to keep it on your table. Honestly, those rubber feet have serious traction i.e i have a train track nearby that usually shakes the hell of everything on my bedside table, this lamp doesn't give a s*** about it and stays firmly in place.

Downsides (or what I've read) :
I read quite a bit online to see if there were any glaring issues with the product. What I've found :
-button placement hard to find:
FALSE, the buttons are placed on the edge of the product so looking directly at the product(like looking at the time display) you can't really see them since you would only be seeing the height of the button/ travel distance of the button. It's true you have to grope around a little to find the correct button but I don't feel this is a problem. 1. they are well spaced (see pictures) 2. the buttons that are grouped up (radio and brightness) have a high ridge separating each button of the group so you can easily distinguish the different buttons (see pictures with 3 buttons close up).
-12h to 24h switch complicated:
FALSE, the manual that comes with the product has extremely clear instructions of how to change it between 12h and 24h setting.
-disappointing waves (sounds):
TRUE, this is the sad one. One of the available 5 sounds that can be chosen instead of the radio, is supposed to be waves/ocean sounds. It actually is more of seagulls squealing with a little bit of waves in the background. However, there are 4 other choices which you should be able to find something to float your boat (satisfaction).

Final thoughts:
The display has various brightness settings that can make it very dim. The display menu to set alarm/clock time/brightness/etc. is very easy to use the only tricky thing can be to touch the buttons (capacitive) which sometimes doesn't register your touch or you're not pressing the adequate location, but it's not something I usually play a lot with since I dont constantly change my settings. Also, it usually takes 1 failed attempt to get a good feel of where to press so it registers on all following attempts. Also, I wouldn't recommend using this as a night lamp replacement to read from a book. I feel the light it shines is too diffuse. Don't get me wrong the light can get very bright but it's all over the place so to read from a book(paper) using only this product as lighting may require some fancy footwork or positioning to get the right angle to have enough light.
So, this product has met everything specified by the manufacturer, the manual is crystal clear, everything works as advertised and it works for me. I highly recommend this product if you have trouble going to sleep / waking up. This product has no marketing scams that I have found. If it goes on sale buy it and enjoy!
