Needed it in a hurry and used it the minute I got it. There is no doubt that it`s very practical for local communication project. No project postponed. Easy use, precise results.

It`s working with only one to two meters error when locating the broken point, so much better than expected.

I used it twice after I received it and it worked as expected, completely satisfying the testing needs of my project.

I need a cheap OTDR, the sales recommended this brand to me. It works as expectation, thanks!

They worked perfect for the optical fiber measurement!
