### ⭐⭐⭐⭐⭐ Great help for cleaning up after puppy.
*by S***D on January 19, 2026*

This is so helpful. Have a puppy and can see where he peed. Makes it easier to use my rug cleaner in the right area.

### ⭐⭐⭐⭐⭐ This light has so many uses!!
*by M***S on January 30, 2026*

This light is PERFECT when looking for a pee smell!! Takes small batteries and very bright! Its so great to have one of these if you have cats inside when they aren't all they way

### ⭐⭐⭐⭐⭐ BEST BUY EVER!!
*by E***L on July 9, 2025*

This this is AWESOME!! it's great value for the money!! The battery life is incredible! The heat level gets kinda warm but nothing that can't be sent with. It's was the perfect size for what I needed. My mom found a dead baby horseshoe crab on the beach & gave it to my son, so I put I resin but I had to do it slowly and one level at a time. I did it on a day that has NO sun so having this light was a HUGE save!! Then I was able to prop the light up to go over the top, THAT was how it got so warm. But it was still awesome. I highly recommend you buy this, especially if you do a lot with resin
