to one of my biker friends two others. The dots will wear out if there's solvent next to them, even though they look COOL so I balance my tires with them.
Not much to rate; that's four packs of valve caps in the shape of cubes. They appear to be well made and the finish is nice. They have metal threads and are easy to screw on and off the valve stem. I got them to add something to my BMX bike.
I put it on my Mustang the next day when I left the tires flat. I wouldn't recommend them to anyone, it can be dangerous to drive on the road and tires don't get you anywhere.
