Quite possibly the cheapest micrometer money can buy !
Metric – 0 to 25mm ( analog )
Operation is a little on the rough side ( not the smoothest in operation ) ..
I did some cleaning and oiling and the micrometer is a lot smoother now .
For the princely sum of $8.76 ( Ozzi bananas ) I just did not know what to expect .
Since I recently acquired a 25mm gauge ( 24.995mm ) , I did a quick check to see how bad the accuracy might be ..
I figure if its going to be out , it will most likely show at the end of the measuring spectrum .. ( The further from 0 the greater the error ? )
The Mitutoyo set me back a weeks wages several decades ago , and the Cheap as Maca’s Chinese Micrometer was $8.76 Ozzi … ( $6.62 USD )
The Cheap as chips micrometer was very repeatable ( got the same measurement time and time again )
The only problem is the lack of smoothness ..
The one thing a micrometer has to be besides accurate is smooth ( to get repeatable measurements ) ..
And that is where these fail some what ..
If you are an experienced hand at using Micrometers , then it may not be an issue for you ..
But if you are not really adept at picking up on problems with measuring , then this particular sample might be problematic ..
I certainly did not buy these to replace my Mitutoyo , but I was very interested in seeing what you got for your maca’s money !
Always remember , the easiest thing in the world to do , is to expel hot air from your lungs and through some vocal chords ..
The resulting sound may , or may not be worth listening too ….
