It’s made by Satisfye, who made a great grip add on for the Switch. I play 99% of the time in handheld mode, and supposedly it makes it more ergonomic. It’s a little pricey though, so before I commit I wanted to see peoples’ opinions on it. I’m primarily concerned about making it more comfortable so my hands stop aching.
If you remember, please let me know what you think of it. I watched the designer/owner’s video showcase on it, and it sounds great. But for the price, it would have to be a significant upgrade ergonomically for it to be worth it.
