Good quality and value micrometer
Seems well made for the price and good for home workshop use. Smooth action and test measurements have been accurate.

works well
for the price this works very well and the plastic box it comes in is of much better quality than you would expect . It will do the job nicely for an instrument that will be used occasionally and no chance of a flat battery when I do need to measure something .

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.

Why pay more for a big brand name that are probably made in China anyway?
Impossible to fault. The micrometer feels robust, the movement is very smooth and it checks out 100% accurate against my Sheffield made Moore & Wright micrometers. Incredible value at less than £15.

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.

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.
