They're not too bad. It's 6 points to solder but the problem is that the solder points on the DVD unit are about half a mm square 
                          
                          The chip only fakes the signal from the DVD, not changing the wii bios so it's not currently detectable 
                          
                          Boots backups straight away, not disk swaps etc.
                          
                          The chip I got is the wiikey.
