### ⭐⭐⭐⭐⭐ 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.

### ⭐⭐⭐⭐⭐ Great for illuminating glow in the dark toys
*by P***K on January 18, 2025*

I 3D print with glow in the dark PLA and this light works instantly to "charge up" the glowing material. It's perfect for glowing crafts and the battery seemed to last a couple of months with occasional use.

### ⭐⭐⭐⭐⭐ 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
