Argh, wires!Overall, I think you should get a butterfly vibrator! They're really great. However, get a wireless one! And also, try to find one that has a little more oomph to it!
First of all, it's wired! No one wants wires getting in the way during sex. That is my main concern with this toy. It can get snagged and pulled away from your body, tangled in your legs, and it just never seems to be in a "good" place. Do yourself a favor and invest in a wireless alternative. You want to eliminate the awkward repositioning due to wires if at all possible and the solution would be to go wireless! This toy would be so much better wireless. It is already challenging enough to keep the little butterfly in place over your clitoris, so the last thing you want is a wire that can be snagged, pulling the toy away from position.
Additionally, it's not super powerful. I'd say to give it a go for beginners, but for anyone who really wants a good buzz, give it a pass. When buying sex toys like this, I think it is most definitely worth it to invest. Especially at the price this is offered, you do not have to spend too much more to get something that is a lot better quality and more fun to use!
This is something you are going to want to be using with your partner. Do not settle for something subpar. Get something with power and that gives you options (it is hard to have too much fun with the wires in the way). You will thank yourself for it later!
