DS(9) has been asking for one of these for two whole years - he says it’s all he wants for Christmas and he will do without any other toys (fine by me as we’re trying to reduce our buying of plastic tat down to nothing) . Trouble is I have no idea what to buy ! I’ve been Googling but none the wiser 
Does anyone have one ? what should I get ? He has an x box so I guess one compatible with that.
