Svakom Trysta สีแดงพลัม

The rolling head inside the silicone shell is what sold me, and it actually hits the right angle without any awkward wrist work. Charges fast too, and the vibration is strong enough that I don't need to crank it past the first setting.

Wasn't sure about the rolling head at first but it actually reaches the right spot way better than my old one. Charge lasts a good while too. Only gripe is the silicone picks up lint like crazy, so rinse it before each use.

The rolling head is a neat idea and definitely different from a standard vibrator, but I found the angle awkward to hold for long. It's plenty powerful for the price, just not as easy to maneuver as I'd hoped.
