I was pretty excited to have a cheaper option for panel lights, but it was just a disappointment. 2 of the 6 Pamela had color issues -one of them was HORRIBLE with color bleed (when I chose yellow, there was green on 2 corners of the panel!).Definitely wasn't worth it, sending back ?Bought these for my daughters room. She loves them. I recommend.Would not recommend AT ALL. Stopped working entirely after one month with just normal use.Imposible no tengo como probar sin conexionesThese lights are very nice to look at and quite bright, almost to the point that I wish there was a dedicated 'dimming' control on them. The different modes are nice, although the audio reactive mode wasn't very appealing and was more of a strobe effect with colors.These lights offer a great competitive price and product compared to the brand that everyone already knows. They come in at such an affordable price it's worth it to ignore the few quality issues I ran into. I use these as accent lights in my living room area and they work pretty great. No issues with the controller or app / smart features at all. I like the app, its easy to use and easy to customize, I see alot of features in there that I wont really use but they're nice to have. I usually keep them on a fading gradient of white and blue, this is kind of where some issues come up with the quality.Occasionally on the white, there's an obvious color difference between the panels, its very subtle, nothing like I've seen from the other reviews. It's just slightly off but with someone like me who's quite particular it bothers me. I tend not to look at it since it's off to the side so it's not as annoying and I doubt other's will notice it so its not enough to return it. Secondly, when I installed the lights, the film that is on the front to diffuse the light came off one of the panels, a bit of quality control lacking there but it was easy to super glue it back on, no issue there.Overall I really do these lights are great for the price, I really do like them, just maybe not to look at them... Really though you shouldn't be putting bright lights in front of your face or even within view as its distracting anyways. The quality obviously may have some issues, but again in my experience its either fixable or ignore-able and those are probably the type of issues you want from a "cheaper" budget product rather than functional issues. They get 4 stars, they're nice and bright, app and features are great, overall an almost 5 star product if it wasnt for the off-white shades from one of the panels. Would I buy them again? Probably if I really needed more panels..I only had experience with the cheap hexagon lights (The ones in the $30-$50 range), and compared to those these are so much nicer!I did not use the app, I went through the clickable settings on the side and really enjoyed the version where the colors slide/fade across in a gradient.The blues, greens, yellows and purple gradient comes out pretty seemlessly on that setting. When it comes to red the gradient is less seemless so color jumps are more noticable BUT my pictures make the red fade/gradient seem a lot more noticable than it actually is.It looks really nice, I like it quite a lot!My only real complaint would be you have to know where you're setting this up, it's best not to connect everything together than try to move it on a wall.When you connect the triangles, they are connected semi-loosely, because the only thing holding them together is the little tab that tells each triangle it's connected to another one.The light is great. Looks cool on my wall. It wasn’t too difficult to install. It sticks to the wall with two sided tape. Each triangle is connected to the other with a small flat connector. They come in a pair that needs to be broken in half. I set mine up in a circular pattern which caused a bit of problem inserting the last piece as it had to do connect to the prior and the first one. It took a little wiggle to get it done.There is the Yeelink app and the Mi home app which both require registration. I can’t imagine buying a house these days or even selling mine - all the lights, all the plugs all the switches all tied to accounts on a dozens of different apps. If it wasn’t for Alexa to tie these all together for me I would be lost. Alexa turns on this light, changes the colors and will set the brightness from 1% to 100%. These wall tiles are a bit expensive and I recommend getting two sets to get the full effect. Even at bright yellow at 100% it won’t light up the room. This light creates atmosphere, not visibility.If you found this review helpful, click below and let me know.
