I give it a 4 because I haven't had much use for it. The magic want steals the thunder. My wife doesn't get a kick out of it either. So while the product itself is awesome, and does great just as a cock ring ... the vibrations haven't helped (us). But hands down I'd recommend others to buy and try it, worth it.
I bought the black Tor2 for myself and my boyfriend and we are both so pleased with it, it’s very powerful and we love trying out all the different settings, it certainly has made a great difference to our sex life and I would definitely recommend this product!
