I like that it's cheaper than a $20 or $10 skate tool Should be at any skate shop if I've used one is it's a pretty cheap tool, well worth the money. Make sure you use some type of oil like 3 and 1 or wd 40. Center the tool on any damaged or worn protectors, use a wrench and start turning but before turning, spray the tool with oil and start pedaling, then wipe and you're done!
