Quality just isn’t there
Color: 3000K Warm, Size: 2Roll x 16.4ft
Was very excited to receive this product because I had difficulty lighting op these LED strip lights, this looks like a package that had everything that I needed. First off, the strip lights themselves are very thin with wise and would look funny on my project, the adhesive backing did not stick at all once removed The touch sensor works great for about 10 minutes and then completely died, overall not impressed with the quality of this product, sending back

Excellent Cabinet Lights!
Color: 3000K Warm, Size: 1Roll x 16.4ft
Great cabinet lights. Easy to install and connect. The touch less control is handy and works well to dim and turn the lights on and off. Been using them for half a year now. No complaints.

if you are going to be moving them a lot, buy something more sturdy.
Color: Black, Size: Wheel-6 Panel
I use these at our churchc. They are pretty good, not terribly study and the screw that hold the faabric have pulled out in a couple of places. But they wqould work especially well if you were not constantly moving them as we do. They are a bit of a pain to assemble.
