I know some people would prefer to buy the official X-Box version of this, but if you're on a budget or just not concerned with names, I think this is a fantastic purchase at a quarter of the price - particularly as youre realistically only likely to use it once or twice!
It feels robust and sturdy, well made, the handle is comfortable and metal shaft is secure - its proper steel too, not that cheap flakey brittle metal that you get on a lot of cheap screwdrivers. And yes of course after Id finished there were some slight tool marks on the head where the screws had bitten it, but I wouldnt say it was anything to be concerned with, so much as my over-zealous tightening, and Im confident it would certainly hold up for several more uses.
One word of advice though - The reason I bought it was that my B button was sticking, preventing me playing several games; so I wanted to take it apart and find out what was sticking it. Now Ive never opened one before - maybe you have and/or know already - but on first inspection there looks to be just 6 screws - however there is a 7th screw UNDER the barcode sticker inside the battery compartment. I warn this because the sticker on mine was so flat that I wouldnt have noticed the screw hole had I not been poking around - so if youre taking yours apart - make sure you account for that one or you risk damaging the casing!
