The step by step instruction page is pretty clear and it's not that difficult.
We agreed it was not something to try on a first date due to the fact that it takes a few minutes to figure out, but with time it'll get better with practice. It took a little bit to find the best position for insertion (squatting), and getting it placed in properly. It's a little different seeing the ring and it takes a little bit to get everything aligned, but once there, it's great. She said it felt like her vj was tighter after insertion and it was a good thing. Ease of use: 7 out of 10.
Cost: A multi-pack cost the same as a pack of Magnums, so it's not an issue.
Convenience: Both Fascinations and Castle carry them locally (in PHX), as well as Amazon for better volume discounts. Instead of carrying a range of sizes, one is all you need, and a lot less suspicious than a bag of different rubbers. We're giving it 8 out of 10
To the big issue of how it felt and worked: In one word: INCREDIBLE. We both agreed it was like going totally bareback. She loved seeing my uncovered tool going in and out. I couldn't tell there was anything there. Make sure to bring plenty of lubricant, once we used a generous amount of coconut oil, it was a blast. No more sensation-killing male condoms for us. As we talked about it afterwards, the decision was it would definitely be the way to go for a party of three or more. I didn't try DATY with it in, but it shouldn't be an issue to move the FC out of the way. Should she need to urinate, same thing. easy to move out of the way. Utility: 9+ out of 10.
Overall: Not really good for a 1st date experience with someone who has never used one. Once you have a level of comfort with each other, then it's the only way to go. For steady partners, it is definitely better than sliced bread!!
