Engine Compression Tester 1 Piece Set
Disappointed that the product description does not indicate the plug sizes which this tester will fit.
It does not fit 10 or 12mm plug threads and is therefore no use at all for my purpose.

Easy to use
The detachable hose makes it easy to attach to the engine. Dual 10/14 mm connectors is a neat idea, but I have only used the 14mm so far.
I don't know how accurate or repeatable the gauge is. But for diagnosing a bad cylinder its just fine.
Gauge is a sturdy item well protected in its rubber boot. Lacks a case to keep it in which would round it off perfectly. But for the money you can appreciate why it don't have one.

Up to the job
Does exactly what you would expect a compression tester to do. Quality appears good.

Does what it should!
Works well and like it holding the reading! The main disappointment is a sealing o ring which doesn't stay in place and keeps falling out so easily lost. A spare is provided but sadly mine was broken!
