there good and bad i have one and it has fallen while i was jacking my 89 up on the trail.....sacred me 2 death. make shure you stick a beefy log or rock(s) under a tire, as a wheel chalk.i have also been useing it in rain, had the handle slip and start letting its self down...scary too. the cheapy ones are bad, my friend got one and we tryed to use it as a winch, it sent the strap across his xj beacuse the cheesey springs gave. if you have to have one, spend the extra $$$ dont kill yourself beacuse you decided to cheap out. like stated, handy to have but dangerous and a PITA
