Works as advertised; very lightweight, portable and easy to use.
Works as advertised and as reviewed by others. Amazingly lightweight and compact. Very easy to move, set up and operate, and works well with the solo feeder. Pitches the standard dimpled plastic pitching machine balls consistently at the same spot. My only worry was whether the Jr. Hack Attack would provide enough speed for high-level 18U travel players, but found out that it provides plenty of speed. Plus we have is set up at about 30 feet, so we are not even near the top-end speed. Have only had it a month, but at this point I couldn't see a need to get the larger version if you are just planning on pitching dimpled pitching machine balls, and especially if you don't plan it use it heavily. You might consider spending extra to purchase the full-size Hack Attack, however, if you plan real heavy-duty use and/or want to pitch actual softballs since they substantially heavier (although I haven't tried actual softballs).
