## Customer Reviews

### ⭐⭐⭐⭐⭐ Just what I was looking for
*by K***B on January 25, 2023*

Thought our 9 year old Christmas tree would never light again. Found this adaptor and it works beautifully.

### ⭐⭐⭐⭐⭐ Best quality undercounter lights I've found!
*by G***E on May 26, 2022*

These are bright! They include an ON-OFF and dimmer. I've had some installed for YEARS without a problem. Easily attached with 3M VHB tape. Great product!

### ⭐⭐⭐⭐⭐ works great
*by R***M on December 31, 2013*

I originally ordered a 3 light strip kit to install under the shelf over my desk. The lights were so bright I only needed on strip. I ordered a second power supply and switch/dimmer to install under our hanging kitchen cabinets where we needed more light. Both application work very well. I recommend using 3M picture hanging peel and stick strips to install the lights strips, switch and power supply. It's much easier than dealing with all those little screws. =The lights create a nice warm light and when turned all the way down make a great night light.
