This is one of the best toys my girlfriend and I have used together. I would say that for anal play it may be a little big for some beginners but if you're looking for something bigger to move to intermediate or advance with a few extra bells and whistles this is it. It's a great toy whether you use the vibrator option or not. It's sure to please either way. The veins and texture of the Dual flexi-dong|Dual vibrating flexi-dong are a nice addition if you’re looking for something textured and would excite anyone.

The multi-speed settings for the vibrator are perfect. From a full on, strong non-stop stimulation to short intermittent bursts, it doesn’t disappoint. Four speeds may not seem enough to some but each setting is different enough so that you'll find one that suits you. But again, it may be a tad too much if this is your first sex toy. It’s also not too loud as to make you think you were alerting the entire household to the fact that you just turned your vibrator on. The control button is placed in such a way that if you're not careful and aware of it you will hit it many times over and over again, it’s quite sensitive. Not much of a problem if you're using it alone but can definitely affect things if used with a partner and the speed keeps changing when you don’t want it to. If you don’t want the vibrator on I recommend taking the batteries out as you could easily hit the button and get a bit of a surprise when the vibrator comes on and you’re not expecting it.

It's quite flexible but not quite to degree shown on the packaging. The spine inside as limited mobility and bends a little bit beyond the position that it’s packaged in. If bent or twisted a little too much during the heat of the moment you could dislocated a vertebrae out of alignment which happened to us. You can pop it back in place but it's not easy and takes quite a bit of muscle and luck. If you are aware of this you shouldn’t have any problems.

If you’re aware of this it shouldn’t happen and it is quite strong and does have plenty of movement to make this comfortable enough to use with someone else in various positions.
