## Customer Reviews

### ⭐⭐⭐⭐⭐ Works great.
*by C***C on April 26, 2020*

My original batteries for my laser cartridge had died. This not only got me new batteries but also extra batteries and spare parts. The price was a very good value.

### ⭐⭐⭐⭐⭐ Perfect fit!
*by E***. on December 31, 2024*

I had my fingers crossed when I ordered this replacement kit, but the "o" rings and batteries were a perfect fit!

### ⭐ Was not happy
