This product was a surprise. I had low expectations of it, especially for solo play. But the vibrations are strong and gratifying. Having a sleeve feels really nice and combined with prostate toys takes it to the next level. Downsides are battery life is too short. And the power button requires you to remove the vibe from the sleeve to turn on and off. Left idle in the on state drains the battery relatively fast. Future iteration of this product I would increase battery life and make it so that the power button is accessible without removing the sleeve and fishing out the vibe.
