The thing is really top, the registration code is 1 2 3 4 and the operator code 1 2 3 4 5 6 is not listed anywhere. It works perfectly if you buy the batteries, which cost another 1000 €. Unfortunately, my display was broken, but I think that can be sorted out; otherwise, everything is top at a top price for a top device.
