I was really pleased to buy this. I had been searching for one for months as a previous model I had (by a different manufacturer) burnt out (overuse? Probably). This one is different. It is beautifully made with a soft, silky feel on the outside and a ribbed inner surface. The stretchy material is very comfortable to wear. The flexible wings wrap around your penis with just the right amount of tension, but are easily gripped to increase stimulation.It has a quiet motor you will not notice, and nine variable speeds going from smooth to pulsating that are a delicious treat for your mind as well as your body. If you are not so keen on fully enclosed masturbators, which I find can be a bit dulling, then this is the ideal choice. Great for foreplay and solo action, allowing for full hand control. The combination of a textured inner surface and energetic vibrations intensifies your sensations from tip to balls to give you a full on exploding experience. The phone app makes it easy to change speeds with a single finger swipe. Let's hope I don't wear this one out.Another reason I like this toy so much is that I can slip it under my trousers and let it buzz away gently while I work at home, giving my penis every delight while I concentrate on the boring stuff. The contrast is stimulating to say the least. Waterproof and easily washable. Amazing value for the price. Highly recommended.
