Hi Tammy, I have had mine in since the dive season started and yes, it is well worth it. Long dive days in places with no bathrooms or port-o-potty's makes having a She-P well worth it.
I ordered the She-P while I was waiting for my suit to have the p-valve installed. I practiced with it on land a time or two just to make sure that I could attach it correctly when the time was right. The first time I used the She-P in the drysuit it was a complete success. The second and third time, utter failures. Since then, it has been better and I have not had a failure again. The failures were operator error, not enough glue on the "rear" side and to much glue all over the other time. To be safe, I have used Poise pads just in case there is a leak. I will eventually stop using them as I get more comfortable with making sure that it is attached and not going anywhere.
And shaving is better than waxing since waxing required more growth to remove the hair.
I also found that the glue remover pad irritate my skin if I do not wash it off after I get rid of the glue on my skin. The stuff if potent as it removed my nail polish one day after a dive.
Have panties that are dive panties because the glue is strong and does not come off in the wash. It can get everywhere if you are not careful.
Good luck with it though. I have found that along with the drysuit, dry gloves, and hot socks, the p valve/she-p has really been a major improvement to my diving comfort.
