The problem is I don't have tens of thousands to buy a high end version of all the stuff I use so will be ordering another cheapo as I'll get a refund for the damaged one if that breaks as well I may start wondering but I can't be that unlucky can I?
I bought a 300mm digital caliper new for £18 which needed the zero button pressing 10x for it to zero. I got a refund for thatbought another from a diferent seller and that works perfectly in my Z axis DRO.. still only cost me £18 but is a bit of a pain chasing refunds sometimes… you have to be dilligent.
Sometimes you can buy expensive stuff and that doesn't work either £70 for and ER20 collet set – no good but has been refunded.
