I have used these for over 10 years as well as natural sheep skin chamois. This works very well. If you wring it out (edges too) it doesn't streak, leave water behind, and works about as well as a natural chamois. It will also last for years if left damp and stored in the plastic container, (nope don't dry it). Then why use a natural chamois?  Well for me there is something about the shine left behind with a natural chamois. I'm 69 years old and have used those since a teenager. Now that maybe just a memory lane thing since this works just fine. If you don't want to dry, and as I do stretch and soften a natural chamois after use, then get this. It works very well, plus I have never found anything synthetic, that works as well. (Believe me I've tried a lot different ones too. Haaa)  I do recommend it. Hope this helps someone.
