Works as expected. I bit aggessive so extra sensitive individuals might not like it but if you like the extra stimulation go for it.
I bought this for my bf for Valentine’s Day. Not sure if it was the specific sensation (Thunder) I brought but he wasn’t into it that much. He said he couldn’t really feel any difference and that it gives a more cold feeling as opposed to the warmth of a mouth or actual vagina. I wouldn’t purchase this one again but maybe we’ll try a different one next time.
