All-in-one Fiber Optical Power Meter Fiber Optic Cable Tester -70 to +10 and model 1 KM Visual Fault Locator Portable Optical Power Meter with SC and FC Connector Fiber Tester Tool Equipment

Cheap and cheerful, but does the job. Only problem is that the testing terminal for contiguity (red light) comes loose. It has a screw cap which with use causes the nut securing it in place inside the housing to come loose. I bought a replacement because the loose terminal actually broke fell out of the casing, and within a month that one had already come loose. I opened the casing to tighten it, but It is very awkward to access the nut. With a small screw driver I was able to gradually turn the nut until it gripped and then applied some silicone to prevent it moving again.

Defective item. Returned.

Probably ok but seems cheeply made, sent mine back as it had missing digits on the digital read out, not ideal.

Missing fibre connectors . Very poor ? English ? Instruction sheet . Not ideal for what I thought it should be capable of . Sometimes the price is too good to be true..

Not very accurate, more than 2dbm difference from my other power meter! Ok for an average dbm but not for accurate work
