Definitely stick with mitty-witty-tuyo when it comes to hand measuring equipment, I've put mine through hell, the only thing that's prone to wear is the thumb wheel insert for the Vernier.
The batteries seem to be magic as i'm still on the first and I ALWAYS forget to turn it off.
The only advice I can give is with buying, if the price looks too good to be true, then it probably is, always stick with the approved suppliers to avoid the disappointment of buying a fake,
it's worth it to just buck up and pay the cash, I've found.
