Well I might as well report my experience with it. I did receive it, but took precautions not to use it on a quality LP to test it. I tried an older, dirty LP, which I listened to beforehand, many pops, ticks, etc. I used this new gizmo, I didn't notice that it left any residue that I could see, but it was very sticky while using it. I was hopeful that this was picking up lots of stuck residue and grunge.
Afterwards I listened again and I could tell no audible difference. Certainly not anymore noise, as Clio09 suggests, but no less noise either. I did clean my stylus after use. My experience would not lead me to try it any further, though I did not throw it away. It says is works to clean plasma screens too, so I may give it a try there. To me, if it does not improve things, I don't want to risk using it if it is possible that it could leave a residue which I cannot see, but may build up on the stylus. I'll stick with my carbon fiber brush for dry cleaning.
