Éva

For most users, yes. Dame refined the wings until a strong majority of testers reported Eva stayed secure in most positions, but it states plainly that fit depends on anatomy & how a couple has sex. Where it needs help, pressure between bodies or a finger keeps it seated. Setting that expectation at the counter avoids returns.

The same thing. Dame renamed Eva II to Eva & only sells the 2nd-generation model; the original was discontinued in 2017. The current version has a top button & no charger hole (it charges in its inductive case); the first generation had a front button & a charging hole.

Water-based lubricant only; Dame advises against silicone-based lubricant on its silicone toys. Dame Aloe Lube is the match. Dame warranties Eva for 3 years against defects with proof of purchase; Sexy Living retailers send us a photo or video & we handle the replacement.
