FINAL UPDATE: Seller shipped new power unit and it works great now. The lights are really great and super easy to cut to size and use. UPDATE 1: Seller got in touch and is sending replacement power unit. Will update again once it arrives. I do really like the look of these and they did wonders for a dark park of my closet that has built-ins. ORIGINAL: Lights stopped working after about 6 weeks (beyond the 30 day return policy). Seems like the control unit died. Haven’t found any feasible way to contact seller or manufacturer. Will update review if anything changes.

Light it up!

Color: 3000K Warm, Size: 2Roll x 16.4ft, Color: 3000K Warm, Size: 2Roll x 16.4ft

I am very happy with these. They are easy to use. The only reason I am not giving a five star review is because the instructions and assembly weren’t the easiest. At first we could not get them to work. After looking through the reviews, one man told us that the -\+ were backwards and we tried what he suggested and they worked. I do suggest that because there are two light reels there should be two connecter boxes as well. We had to purchase two packages. Overall, We are satisfied with our purchase.

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.
