Got this for my son to use while he was having his Joycons repaired. He tells me it paired easily to his Switch, has no controller drift, is responsive and fast, and has no issues at all with it. Build quality is nice and sturdy without being overly bulky or heavy. He is continuing to use it even after getting his other controllers back and recently found out it works for playing games on his Windows 10 computer when connected by the charging cord, so win win! Works great for Steam games!
I'm going to try and see if it will connect to my Nvidia Shield Pro as a second controller. If it does I will be ordering a few more for family game nights!
