We switched to spring powered blasters at our arena. Us having to deal with charging these and them overheating or running out of charge was just too much of a headache for us. But this lot would be great for running much smaller parties. Ours were always 20+ so these just couldn't keep up. Everything should work. Lot includes 30 gel blaster surge which retail for $49.99. Also have a ton of extra barrels to change the velocity and about 50 of the hoppers. This lot would retail for over $1500, but it's just taking up space at this point. So if you can make it work for you, or you want to start a small mobile business this would be perfect!
