Not so great - Hoppe's 9 Boresnake Viper Den Cleaning Kit for Rifle

Great concept, but this does not live up to what it promises. After using this snake with Hoppes bore cleaner, I then ran patches through the bore and found that there was still significant powder and cooper residue. I tried this on both new and old rifles all with the same result. So, it's a good idea, but they just do not clean the bore as I'd hoped. I'd spend less money on the non-viper version and finish cleaning with brushes and patches.
