Satisfyer - Sunray App-Controlled Clitoral Air G Spot Dual Stimulator

Below are my impressions after using it the first time.
Minus points:
- There was NO charger to plug the USB in. Seriously? Who carries around a USB charger all the time or a laptop? You should supply not just the USB wire but the wall charger in which it should go in as well.
- The steps of functions are not as intuitive and how to change something doesn't seem to be simple. We still don't know exactly how many times and/or for how long exactly one needs to press what to change what, and how. We wanted to have AdultFun, not spend the time in a practical tutorial in "Functions and Specifications of a Dildo". At the end we fumbled with it more than 10 min. until we finally managed to switch it off!! Not only the operation should be simpler, but also a better description of how to use it should be given clearer and in much detail in the minuscule flimsy sheet of paper that passes as instructions.
- Why does it need to have an app? You think one will stop when one is in the heat of passion, to move aside from the lover to start instead fumbling with the phone with wet/lube-greasy hands? Really?? In my opinion, all functions should be obtained only from the buttons on it, and in an easy, fast & intuitive manner (see previous comment)
Plus point:
- Battery life seems to be very good; we used it for approx. 4 hours almost continuously and it didn't discharge (though cannot tell how much it discharged/how much battery was still left, because there is no indicator).
