Seems well made
I've only just had this a few days but it seems well made and accurate, which is all you want.
User
9/10 - well made, easy to use, repeatable.
I'd rate this a 10/10 if it came with more instructions, otherwise I think you're getting everything you get with a high end micrometer for a very reasonable price. The measurements are clear to read and repeat the same every time down to 0.01mm. I'm very happy.

Good value
Good value for money, but the caliper bit on mine is a tiny bit skew and the zero-ing is finicky. It will work for most applications but if you want razor sharp accuracy there are probably better, albeit expensive, options.
User
Nice quality. Why buy something needing a battery when it's this cheap?
Excellent, well made, simple to use, no batteries required!If you're new to this analogue technology then read the instructions first.

Nicely made, feels good but not accurate
Looks and feels very well made but it's not quite accurate, being out by about 0.03. I'm looking for a better one, which will probably cost considerably more.

Buon prodotto
Prodotto di ottimo rapporto qualità prezzo. Semplice da utilizzare, mancano istruzioni ma abbastanza intuitivo se si ha un minimo di familiarità con il genere
