They're good for being cheap, but certainly not "great". They're cheap chrome steel, so they rust, and they're not strong enough (or long enough) to do the job as easily as some other (more expensive) tire spoons. A third rim guard would be a welcome addition to this tool kit as with these little scoops and just two guards you can SAFELY scratch the rims when mounting/removing tires. However, this set is a decent value for what you pay.
