If you need the ring I don't blame you. You of course know you will find what works and doesn't. It took me awhile. That's for sure.
All I use is a little paste for caution and barrier spray. I'm fortunate that's all I need. I worried myself sick prior to gettin one. And all for nothing. I just remember trying the ring instead of paste and it was a mess! A wafer comes off pretty easy after 3-4 days but to take it off only after a few hours. Ugh. I thought I was gonna rip my skin off! I found a spray releaser after that. Worth it's weight in gold to me. Wafers drop right off with it.
