I have the RhinoBlock, had it for a few years, still on my original core.
Shot the Matrix last year or two years ago for deer management quals - not my target, one of the bowhunters bought one for the ability to replace the blocks.
There's about 15-20 bowhunters shooting at this qual event 3 arrows each, and 20 and 30 yards - around 100 to 150 arrows shot in the session with practice heads.
The Matrix was probably shot by half of us - it held up, but like any target you actually use, it showed the use.
Pretty easy to swap the shot up center out for another hex, and keep shooting - which is what their market target is.
I read this thread when I was looking at one a few years ago - it's continued on from 2017.
