Quick update.
Installation as with most loaders unless you are happy fiddling inside it do not try, get someone who is to do it for you. But it is not too bad, I had 1 minor issue when I had not correctly fitted the ribbon and it slipped out, soon noticed and was easily fixed.
Performance:
Great. Personally I prefer the button to the switch just because I am less likely to accidently leave it switched on after playing. The extra settings are easy to tweak and the usb is also easy to access when you want to use that.
It is a luxury item but I like it
