Working as expected
Used it four times now, it's doing the job. Doesn't seem to have any weak points yet.

poor quality bit
I used a suunto increment borer for 12 years with no issues. I still use it.This jim-gem is a piece of crap that lasted literally 50 trees and broke.Don't waste your money.

Not built to last
Works fine to begin with, but not built to last. In coring 150 trees in the past few months, mostly hardwoods, 2 of our 3 JIM-GEM increment borers have broken beyond repair (one got a big chip at the tip, one broke off 1" from the tip). We will not buy this brand again, though it may work OK for pines.
