so far so good. seem durable enough, and the spoons are smooth. i bought 3 and I'm glad i did. having only 2 would have been a hassle. you may want to wrap beneath the spoons with a bit of pvc tape if you are worried about scratching the chrome on the rims.
First off, I recommend buying three of these suckers, as with any other number it becomes super difficult. Had to learn how to use online but the quality of the irons are top notch, well worth the money. If you are a novice it may be worth your time to take it to a shop and have them do it for you, but you won't find a better deal than these if your doing it yourself.
A very sturdy shop tool that is quite easy on the hands. Since these are back-scratcher in length one should not try and put them in their trail-pack, otherwise they are a nicely priced home/shop tool.
