Great price. Super accurate reading. Easy to use great for the field and a quick light check. Only problem is the screen. I’ve purchased this a couple times now and the screen keeps cracking and bleeding. Other than that this is a great product.

I ordered 4 of these as they were cheap and advertised to do the basics as we needed. If they worked good was going to order a bunch more for the group.Out of the 4 that were delivered, one box was missing the LC fiber adapter, which made it unusable as almost all of our connections are LC. The other 3 had the adapter and were immediately usable. The fiber light works good, I prefer flashing mode and have used it on long single-mode runs and short multi-mode runs. The copper tester at the bottom is super simple, it sends a single from the primary unit via an RJ45 female on the main body and then if the other side of the cable is attached to the removable female RJ45 piece it will go through a sequence where it flashes lights on both sides indicating which pin is lit up. If one is missing you have to just know that based on the timing where it doesn't flash, but it's super simple and anyone who knows anything with cables will find it very useful.I wouldn't trust a cheap unit to provide a real DB reading for fiber loss, however having the capability to detect light that isn't visible is awesome. No more guessing which side is transmit after going through multiple panels, just hold the end up against the unit while looking for loss. Works great on the 1310 and 850, haven't tried it with anything else.Overall, super useful and well designed. Well worth the money. Would like to have had the unit with storage space built in to it for the fiber adapter (and to include more than just the LC adapter). If they had sent 4 out of 4 units with the adapters I would have given it 5 stars.

Bright VFL, flashlight is a regular LED, light readings have been off by up to 2dBm.It's great for checking polarity and circuit continuity, it's very small and easy to use which is nice. Don't expect a calibrated measurement tool.

This enables you to test the strength of the light coming out of fiber when it on, great for troubleshooting.
