Review on 2 Pack Fine Grade Synthetic Clay Bar Sponge for Car Detailing - Large Size, 3x Longer Lasting Than Traditional Clay Blocks - Speed Through Clay Detailing like a Pro with the Perfect Alternative! by Kelvin Hernandez

I had a much more expensive version of this brand. I've only used it once so far but it seems durable and works just as well as the one I've used. I stopped using "real" clay sticks many years ago when I got my hands on one of these plastic sticks. Aside from the cost factor, you no longer have to throw them away because they have been dropped and they last much longer. I'm very careful about what I use on my Corvette and it gets my approval.
