Review: Can't beat it! - I purchased this in December of 2023 so I'm going on two years of using this OPM and it's honestly the best. The manual calibration is great, battery lasts long, and extremely portable. Purchase the Baoshla A-M1315 Optical Light Source and you have yourself a great little Optical Loss Test Kit for a fraction of the cost. I haven't ran into any issues using this OPM, it works just as it should, and the price is simply unbeatable. I definitely recommend to anyone looking for an OPM without having to spend hundreds of dollars. This bad boy is the real deal.
Review: KISS of testers - simple and rugged, nice to test cat 5 also

### ⭐⭐⭐⭐⭐ Good unit for the money
*by K***R on May 16, 2023*

Puts out a wrong laser light and the convenience of a power meter built into the same unit is great. I have had several other units that do the same things separately but I really like having it in one unit. The Ethernet test unit is an added bonus.
