This is the Le'Chatelain violet/rose. The Le'Chatelain has ridges/texture on the tip.
Simple push-button controls: one for vibration, one for e-stim, one for up and one for down. It has 3 modes: Continuous vibration mode, Pulse vibration mode (2 second stimulation with 1 second rests) and Electro mode. Very easy to use, very high quality, and available in the USA only at Current Pleasures!
