You may have heard of the Eva on social media- it is a crowd-funded vibrator that was developed by two women committed to creating well-engineered sex toys.
The design might look a little strange, but form follows function here. The Eva is designed to be a hands-free, non-invasive vibrator that can be worn to provide clitoral stimulation during intercourse. (Or, it can be worn while reading erotica- or whenever you need your hands free!)
The little arms are designed to be tucked under the labia majora, and the outward tension is what holds them in place. This tends to work quite well for sex in certain positions (like when you are laying on your back), but it might not work as well for other positions (like when you are standing with your feet apart).
Since everyone's body shape and labia size are different, the Eva may not work perfectly for everyone-- but it has received very positive reviews from a number of testers with a variety of body types, and the design is quite clever!
Eva is rechargeable, coated in 100% silicone, and has three continuous speeds to choose from. 1.75" tall x 1.375" wide (vibe portion). Arms span 2.125" at widest point.
Available in lavender or aqua.
