Love these K S light strips! Get the app!
Size: 100FT
I like K S led light strips best they last longer and seem brighter then other brands. Make sure you have enough room to connect them at the plug ends to the box controller they are short there’s not a lot of excess after the light strips to plug into the power box but if you do it right you can do about anything. I like there app over some of the other brands, also I don’t use the remote the signal kind of sucks I use the app and it has a ton of light modes with music beat transparency and flash settings slow, fast, all different colors, and effects. Really sweet pack of lights, if you can think it you can do it with these just don’t bend them on the edges, over lap them like a loop so you don’t break the tiny connector strips in the light or you’ll destroy them ! Ask me how I know. Anyhow these did not disappoint me one bit, even better than expected ! ... show more

Remote was broken, one strip only shows green, 12 LED's not working.
Size: 100FT
Kinda disappointed in these. The remote was broken, the lights on one strand only shows green, and there's about 12 led's out on that 2nd strand as well. I do hope I can get a new set to replace these... bought them July 30th i believe. Moved into my new place and wanted some low lighting.

These lights look really good and are easy to stick on the wall. Its a good price for the length you get. You can also cut the lights to whatever length you want

Good enough
Size: 100FT
They work for the most part. Pretty flimsy, but easy to fix with soldering iron if something gets disconnected. There was one part of the string that was slightly off on each, like the red or the green on the led nodes weren’t working properly. Fine for the price though, you can work around the parts that look off by hiding it or just cutting it off. I do like the convenience of the remote and I like the custom color feature. ... show more

One port for both strips
Size: 100FT
Works great, however theres only one port for both the steips so they both have to be in the same area you couldnt put one in one room and one in another

Bright and Colorful LED Lights
These LED strip lights are bright and offer a great variety of colors. The long length is convenient for decorating a large room, and they create a fun atmosphere. They are easy to use and look great once installed.

Get them
Size: 100FT
I purchased these about a year ago and they are holding up pretty well, I had another pair of led lights the life on them went fast. The app is very easy to use, you can pick so many different lighting options, if you want a certain color you can pick it out. You want your music to line up with them you have the option. They pretty fun to use when you want party lights. They are very stable to use. I recommend these led lights, if you are looking for a good lighting. ... show more

Pretty good, but -
Size: 100FT
I’ve been using these strips in my bedroom for 2 years now. Read the pros AND cons!! PROS: cheap (a must for me), bright, variety of color options. I use the different colors as a form of mental conditioning/re-wiring my brain for my night time routine. Yellow means getting ready for bed. Purple means practicing my music. Orange means journaling. I love the dimmer. I dim a few clicks every 10-20 minutes when I get in bed to slowly go from bright orange to the dimmest orange which has conditioned my brain to get tired and go to sleep. Plus, I match it up with the LED strip on my fish tank, so that’s cool. The remote control is… fine. It does the job. CONS: BE CAREFUL with the adhesive. Once that stuff goes on the wall, **it will peel the paint off when you take it off.** This happened in my bedroom and apartment. However, I did find a solution. Instead of using the adhesive, I use thumb tacks to tack it up around my room. I don’t tack through the actual strip, I use flat tacks just on the top and bottom on the strip. Much easier to fill tiny tiny holes than to re-paint the whole strip area before I move out. Also, the two strips are not separate, but they also are. There’s one plug that goes into the wall, and attached to that wire is a box that you plug BOTH strips into separately. Basically, one goes one way and one goes the other. It’s NOT possible to put one strip in one room and one in another, like I had hoped. However, my bedroom is not enormous or anything so one strip perfectly covered 2 of my bedrooms. One at my parent’s has them because I noticed it was ripping the paint off on removal, so for my apartment I used the tacks. The frequency of my TV remote messes with the color and changes it. Not every button, just a couple (the up arrow, but not the down arrow. The “ok” button, but not the back button etc.). And my last tv remote did the same but different buttons were the trigger for different colors. Weird. But again, for the price, I’ll deal with it just fine. Just change the color back. One last tiny inconvenience - orange is the one I use most and when you dim it all the way down, it turns to just plain red. Ultimately it’s a fine product. Not extraordinary but not horrible. If you know the cons (mostly the adhesive pulling off paint), and can deal with that (like using tacks instead), I’d recommend it. ... show more
