The accelerometer was exceptionally broken on both sides. The BotW's accelerometer aiming was erratic and quickly fell to the ground. Tried to calibrate and reset many things, it just broke. Like most third-party controllers, they felt cheap and bulky. They lacked the weight and density of real Joy-Cons. The vibration was awful, the only real option was to turn it off. The buttons were tight. All in all, this is not a $45 product. I might be ok if I paid $15. Sent back as defective.
