Seems like an interesting concept for handheld gaming on mobiles compared with traditional gamepads. Not sure if the lack of tactile buttons is a good or bad thing given that touchpads give more customisation ability. Thoughts? Don't know the price though couldn't see anything other than a 50% off indicator but no concrete pricing.
It's not particularly revolutionary tech itself. Rather just a Bluetooth touchpad that sticks to the bottom of the phone with suction cups. The important question is how will it go with PUBG and other mobile games? PUBG for example will ban players that use unapproved Bluetooth controllers/companion apps. Probably won't work too well if the rear of your phone is curved.
