What I can say that this is one of the good wireless controller for Nintendo switch!
What I like the most is the Dual Vibration that I feel really strong that make gaming experience is better than if you using the Switch Joycon itself.
Very easy to syncronize to the switch and the battery level is quiet long.
I dont have any problem with the weight, but the I feel like the tumb sticks is too big especially for kids tumbs but it is not a big problem for me.
Overall this controller is great alternative and I will buy some for a gift!
