The TourBox Lite, a left-hand device released in 2024, connects via USB-C. I think the number of buttons is just right, as too many can be difficult to remember. After purchasing it, I realized that the TourBox Elite, which costs nearly 40,000 yen, is the only option for using it with an iPad. Therefore, I've decided to sell the TourBox Lite, which I haven't used much, in order to buy the Elite.
