持久硬漢 充電式 5 功能陰莖環 - 藍色 USB 充電式震動陰莖環 - BL-31902

The ribbed texture on the front adds way more than I expected, and the five functions actually feel distinct instead of being gimmicky. Wore it underneath the balls like the description suggests and the rechargeable battery lasted the whole evening without dying on me.

Wasn't sure a rechargeable ring would hold a charge well, but it ran the whole evening without dying. The five vibration settings actually feel different from each other, not just louder. Wearing it under the balls took a little adjusting but was worth it.

The ribbed texture on the front is a nice touch, and the five functions are more varied than I expected. The USB charging is way better than fiddling with batteries too. Worn it underneath the balls a few times and it stays put.
