Disappointing Quality
I got these floating shelves with LED lights for my wife, and at first, they seemed like a great purchase. She was really excited about them, and they were surprisingly easy to install. Unfortunately, after just two days, the LED lights completely stopped working. It’s really disappointing because the shelves looked great initially, and the added lighting was a nice touch. For the price, I expected much better quality and durability. It’s frustrating when something you’re excited about doesn’t live up to its promise. While the shelves themselves are still usable, the main feature—LED lighting—is what made them special, and that feature failed. I wouldn’t recommend these based on our experience.

LED floating shelves
I love that these have lights. I don't know how they could be designed to hide a cord so are as expected. I wouldn't want them with replaceable batteries either.

Good product!
10/10 would recommend! Super cool and unique. Had a lot more features than expected and good for the price. Super easy to install if you have a hand drill. Very sturdy and not super heavy. Would buy again!

Middle of the road for me. Not great, not horrible.
Size: 10M
Easy to install. Just wanted something simple and inexpensive to liven up my back patio awning. I had them up in mere minutes with adhesive clips. My only complaint is that they are not as bright as one would expect LED lights to be. At night they to me provide more of a soft glow even at the brightest setting. I am not very certain whether they will stand up to hot desert heat. The instructions mentioned adhesive tape on the backs of each light, but there were none on the lights, nor in the box. I used my own. I will update my review after finding out if they do or not. I do like the remote feature however. They are just OK Update**Adhesive tapes were found which fell out of the box onto my floor, which I did not see. My fault. All good now.

Great idea!
Size: 30M
Love the idea of these! Every year it’s such a pain to put up holiday lights that I avoid doing it until the last minute or at all (especially when the weather is yucky…). And I admittedly didn’t get these permanent outdoor lights installed before the holidays as originally planned, so can only speak to the functioning of the lights. I did test the lights and the app -- both functioned well and are easy to set up. I really like that the lights can be put on a timer via the app. Great light color choices as well. Very vibrant. When the weather warms up, I’ll be installing the lights permanently, and REALLY love that I can just keep them up year-round for Christmas, Valentines, Halloween, etc., as well as general every day use. I’ll update this review if installation is a problem, but I am pleased so far with these permanent outdoor lights.
