I realize I'm a little late to this party but I saw your post while researching something else. Our travel team has 3 of the firstpitch machines. My team in particular has been using the same machine for 2 years at least once a week. We throw jugs balls and regular softballs and have had no major problems with the machine. It will throw both 60 mph+. I have clocked it with my radar gun. Minor issues include breaking the on/off switch throwing it into the truck and breaking the plastic handles on the leg tightening bolts. Both issues were easily resolved with a little backyard ingenuity. It is well worth the money.
I found there're 3 types of firstpitch pitching machine namely Firstpitch Baseline, Firstpitch Original and Firstpitch XL. May I know which one of the firstpitch pitching machine that your have? Thanks.
