I wish they would have added two more joy con slots though

My issue is that there seems to be a bothersome issue with the left-side joy con port

I also have the PowerA dock that charges 4 joy-con controllers - love them both

but it has a pretty serious flaw; if you connect it via USB to your Switch base it makes your Switch think the right joy-con is connected

magically my right joy-con is working again

For the same reason that I do not leave the joy-con controllers fully locked in

I like that I can charge a set of joy cons with my pro controller
