I personally own a Wonder Wave and a Vortex and enjoy them both. I tend to prefer the intensity of the Wonder Wave orgasm. It's crazy! I'll put on a porn video and get a little buzzed on some weed and then when I fuck my cock off with the wonder wave, I have the most incredible orgasms. I can cum twice in a row from the same hard on though I still have not managed to keep thrusting at the moment of orgasm with the wonder wave because it's so intense...I just have to stop for a moment as I shoot off; then after the first orgasm subsides I keep feasting my eyes on the porn and pump my cock off again after another 10 minutes or so. I've fucked my WW fleshlight so much I think it's time to order a new sleeve! The Vortex is also a good one. I masturbate multiple times a day and so sometimes I end up using the Vortex when I have already shot a load into my wonder wave. I find that when I've already had a few orgasms during a given day, working my cock with a Vortex gets me going again and I have a nice strong orgasm to finish the day. I go through a lot of lube with both of these toys, but adding some water does work and helps the lube last longer.
