## Customer Reviews

### ⭐⭐⭐⭐⭐ Good range, small spot size
*by B***R on October 19, 2024*

I bought this as an emergency backup for alignment and it’s way better than the $500 laser I bought from McMaster.~.25” spot size @ 100ft(I bought a red and green laser if you’re seeing this twice… it’s a genuine review, both work great)

### ⭐⭐⭐⭐⭐ Exactly What I Was Looking For
*by A***R on April 2, 2023*

This came with an in-depth specifications paper and was well-packaged. Very good item for my purposes. Thanks.

### ⭐ quit too soon.
*by D***H on January 9, 2022*

it arrived I tested it maybe a dozen short times while building the device to use it in and then just before the final install it quit working.
