i like the sound of the zex kit... how much to refill a bottle? and wheere do i even refill the bottle?


Only reason i dont want to go w/ a bottle is because, i want the power there, not some button i hit to give me power for a certain amount of time. Like in a fake racing video game, where you have the "boost" button, then it runs out, and you have to wait to recharge it you know.

but I still dont know if i wanna go w/ a bottle. Again how much to refill them?
