The product is very beautiful in appearance. Qualitatively, it seems quite good and adds a femininity from the design, texture of the material, and the pink color that I love. It offers two functions: i. Vibration ii. Electro-stimulation. Without charging it, I tried it for the first time and noticed the following: The vibration with its programs is perfect! 7 alternating programs (right-left vibration in most programs), each one better than the other. Very satisfied [*****] 5 stars. Unfortunately, however, the electro-stimulation is almost non-existent! On the 3rd level (which is also the strongest), you barely feel some TENS pulses "scratching" your nipples. I expected much more regarding the electro-stimulation from this product. I was completely disappointed! Imagine that the joke-zappers type keychain (usually circulated around 2000-2008 as car keychains) which, although momentarily shocked you literally! [*] 1 star. My opinion is, girls, if you decide to get it, get it only for the vibration. It will excite you! Of course, the company Pretty Love also has a set of two clips (clamps) for the nipples with only vibration that charge (magnetically) separately. (without an integrated cable).
