Anal Electrosex 

My personal opinion

The vibration is not very loud but also not mindblowingly strong. The seven modes are well designed. I'd rate this with 4 of 5.
But I was keen on this thing for the estim. It was the very first(!) experience I made with estim. I am a male sub but always fail to achieve to cum from prostate stimulation. Frustrated I thought I'd give this one a try. I hoped that the e-waves would actually make my prostate erupt in a massive handsfree cumshot. This didn't work (for my part), which I do not blame this toy for. I've read that estim plays out very differently for each person, so I try to be "objective" and rate the estim 3 1/2 of 5.
What I reeeally appreciate is the flexibility. It is soft enough to push it whereever you like, put still hard enough to PUSH on spots. Also the silicon feels nice and I like that it's for charging.

BUT nevertheless I only give three stars while for my part feel like giving just two stars, because:
(1) The feeling itself was unpleasant. It was just contracting my rectrum-muscles which felt neither painful nor thrilling, just weird, as if my ass were kneading a dough. It did'nt reach my prostate. Riding a dildo feels way more hot to me.
(2) I would not be keen to have the highest e-mode on at all, but could easily go like a minute with it. For sadistic aims it's too soft then.
(3) The toy is originally for vaginal use. The brand is "CalExotics" and the product is named "volt electro charge". In the leaflet it says that it's not for anal use. What the ?? (Used it anally anyway cause I trusted meo to know what they say, and they sell it as an anal toy)
(4) It has five estim and seven vibration modes, but you can't see which mode is on. You have to feel it/remember it. There is one power on button, one for vibration and one for estim. If you hold each of the buttons for long, they turn on/off. If you press shortly, it changes to the higher mode, and from the highest mode back to the first. Because you should have skin contact BEFORE switching it on, this insert it and hope it to be not on the strong mode. I also imagine a dom playing this toy on someone else and having no clue which estim-mode is on... The vibration you can might check from the sound, but the estim - either feel it yourself, remember well how often you pressed the buttons or you have to guess

This won't become a favorite of mine anytime soon, but well possible estim at all never will.

Awesome

This was larger than I was expecting, we are still working on getting it in but I like what I see so far
