## Customer Reviews

### ⭐⭐⭐⭐⭐ It just works!
*by A***R on March 25, 2021*

I loved the design of this. One thing I'd change is allowing us to use Feet instead of km. Yeah I can convert it.. but oh well. This product has saved me A LOT of time. now for me it has.. it may not for everyone.. depends on how detailed you need the OTDR to be.

### ⭐ Works fine till you lightly tap it on something.
*by R***E on August 17, 2020*

This is not a quality piece of equipment. The first one I had stopped working and I needed to replace it after I dropped it a literal foot off the ground. The second one barely got wet from a little rain and again stopped working. Its what I expect from crap made in China.

### ⭐⭐⭐⭐⭐ TL290T
*by T***S on May 26, 2020*

I work for an ISO and have been using this OTDR to troubleshoot and ensure spliced connections are correct. Using the OTDR, the Light Meter and Light Source all in one package has saved me a lot of time. The sellers service team have been very good to work with and have answered all of my questions.
