It is not a Grimes, it is a ParX. I have 3 Grimes myself and I shoot them often. And no, they haven't blown up or killed anybody. If you have a draw length 28" or shorter, you will be fine to shoot it. Long draw people shooting in freezing temps did cause a number of the ParX bows to break in the past, but I'm confident if you fit the criteria mentioned above you will be fine.
My Grimes are some of the best shooting bows I own - even by today's standards. I have a 45#, 65# and a 75# Safari. They are very fast and accurate. And you can leave them in a hot car without any adverse effects. I keep the 65# bow in my truck all the time during the summer for quick and/or unexpected bowfishing excursions. TommyBoy
