Zero Tolerance THE REACH - ブルー 13.8 cm USB充電式バイブレーションアナルプラグ - ZE-RS-5094-2

The ringed handle makes positioning way easier than the plain base on my old one, and the girth increase is gradual enough that it doesn't feel like a jump. Charges quickly over USB too, which I didn't expect to care about but now I do.

The curved shaft actually reaches where it's supposed to, which I didn't expect from a rechargeable plug at this price. Girth increases gradually so it's comfortable going in, and the USB charging means no hunting for batteries.

The ringed handle makes it so much easier to control than I expected, and the gradual girth means it's comfortable going in without feeling like I'm fighting it. Battery lasts through a couple sessions before I need to plug it back in.
