Engine Compression Tester 1 Piece Set
not the best
Site doesn't say which size thread this fits. Bought for an e46 m3 and it didn't fit. Pipe could be a bit longer as well. In short should come with attachments to fit different cars. Check before u buy

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.
