I've always use reputable brands like trojan & crown and never the obscure cheap crap. I don't see the reason for skimping this. If you like to have sex a lot & wanna save, I buy in bulk. Yeah I even calculate how many I go thru...so I buy in packs of 100 or even 200.
The thick ones has been good to me in the past. The thinner ones seems ok so far so I'll see how that goes. Whats interesting is I want feel but not finish too soon. The desensitive ones are the worst, it toally desensitives your LB then u can't finish
I have yet to try the sagami 02 which people seem to like here. I am not sure if its even sold in north america.
