Review: Great for price - Great for price and small jobs.
Review: Okay - This is ok… it sends and reads light fine. The OTDR portion is rocky and finding the right settings is rocky as well. I would say if you’re at a point you need an otdr buy a nicer one skip this.

### ⭐⭐⭐⭐⭐ Great for price

### ⭐ do not recommend at all, nor is difficult to contact and has an impossible guarantee
*by W***N on May 23, 2023*

The OTDR testing is a joke, i just purchased a few days ago is not working at all every single reading is showing as horrible.I have cleaned and always use brand new jumpers when testing and this is unaccaeptable. The optical fault locator (VFL) is a bit more difficult to use, because a suitable adapter from the proprietary connector on the device to any official fiber optic connector is missing. At best, you can loosely plug in an FC connector here, but that's not a good idea because once the laser is activated, dangerous laser light would leak out here if the connector slipped. It is a mystery to me why savings were made here, rendering the VFL function useless.
