I have bought 2. Overall, I am satisfied, nice light, I prefer it over LED strips. As for the negatives, I have to mention that the power supply heats up excessively to the point where I had to use my own power supply.

It also states on the packaging that it is dimmable, but I haven't found out exactly how to do that. I asked at the store where I bought them, but even they didn't know how to tell me. The only thing they said is that there might be another dimmer device for this function that can be purchased separately.
