Review on Accusize Steel Block Grade P900 S581 by James Pope

This is a B grade caliper kit: I bought these because I'm an amateur machinist and I don't need the AA grade (or the price tag that goes with it). Each block was individually wrapped in tissue paper and protected with Kosmoline or a similar waxy lubricant. I spent about 40 minutes unboxing each unit and cleaning the WD40. Now that I've had the opportunity to work with each of them, I think they're absolutely worth the price. I assembled a few of them and they all worked as they should. (I won't use them every day but) I'm sure they will work great for my needs.
