They look nice, I'd use them. Only concern is the price point for (correct me if I'm wrong) three pads of the same template? If it were something along the lines of iPhoneX, Galaxy S9, and something else (unsure of top usage statistics off the top of my head), that would make the three pads, and the cost, more appealing. I could see classroom use for UI/UX exercises, perhaps bulk options discounted for educational use should be offered. Just my two cents. Looks good, personally indifferent from a customer standpoint, but a fan of the simple utility and design.
