Bazookas are junk mate, my friend had one, was always fixing something on it.
Before you rush out and buy some cheap Chinese noname buggy invest that bit extra and get something made by a decent company.

Hobao build excellent buggies and this, although it costs a lot more than those ebay things will last 10x as long.

Or this, truggy, good quality and very well priced, for bashing it will be better than a buggy.
