Damn, the stick drift as soon as you got it is unfortunate- I'm also surprised an open box product managed to be that defective. I remember getting a gaming laptop open box around 5 years ago, and from what I remember, it looked pristine and operated without any issues. I've recommended getting tech open box since, though with an experience like yours, I should probably temper my expectations and advice in the future.

But wow, I didn't even know Razer had a controller selling for that much. That's really steep. And yeah, I'm surprised as well more options don't exist, though I suppose it makes sense that the top brands like Microsoft and Razer dominate a market that (from what I imagine) is rather niche, as most people stick to standard Xbox/PS/Switch controllers. It's a shame modularity isn't more popular when it comes to controllers, or other pieces of tech for that matter. It's a real shame products like the Google Ara didn't take off, since those are the kinds of modular devices I'd absolutely love to see setting a mainstream trend.
