In Detail:

The product is very pleasant in penetration and it comes in contact with the inner walls, that of course if the woman is small and/or never had more than 3 fingers regularly.
If you love to be an aggressive girl, this product is not for you.
The battery lasts for two hours at the manufacture declare and it’s water resistant. Also, The app is amazing an functioning (wait there is more), but the remote controller is the down side. The communication is done by wireless chip that placed in the tail, that being put on the clitoris. If a woman decide to closed her legs/put panties/dress up, reception becomes so weak that the the app becomes useless (or in short, open your legs to make it useful). Therefore I do not recommend going out with this Toy – that’s a shame because the main idea is discretion (and ours is to enjoy with you, everywhere).
In general this product is good for the Chinese market or “virgins” and less for BDSM experienced and/or women who love sex on a regular basis.
In conclusion: Nice gimmick with cute app, however In reality not useful  and therefore is a waste of money (around 15 USD).

Comfort: 3/10 (every girl that tried never felt it).
Design: 9/10 (Impress, relatively to a tiny unit).
Practicality: 3/10 (How many “virgins” are there?).
Price: 5/10 (comparatively expensive duo to app development).
Personal Rank: 3/10 (I don’t like giving a present and then hear complaints).

Summary: 4.6/10
After all Leten is very experienced (Chinese) Company in the filled  of adult toy and sometimes that’s not it.
Experiences don’t fit every scenario and it can happen every big company, this time we were disappointment (me and my slave) but there where times we weren’t.
I will never recommend this product to people in the BDSM community but for a virgin girl around age 18, i will.
