I bought this a month ago and the wife and I love it. Great quality and powerful vibration. Only problem for me is that it's incredibly tight fit. Can't use it for very long before cutting off too much circulation. Wish it was a bit bigger. But overall it's good to have.
Bought it as a surprise for my boyfriend and we both loved it! Definitely worth the money but a remote control version would definitely be an improvement. From a design perspective the charger should be black.
