The build quality is good, the cable is supplied in / with an extra small bag with cord to pull, probably for future transference. The only real gripe: It does not seem to matter how rum to connect the cable, but it is hard to see what is the plug down or up. A simple print would help I'll probably myself make a mark Unfortunately, the cable also depends upside to it, thanks to the magnets. I have therefore specially configured a sound that occurs when the cable is properly connected, as you otherwise at the sleeve does not look closed and may end up having the cable off, but no current flows.
After researching the MagNector for the Nexus 10 is unique, there is no other comparable product. This probably has two drawbacks: the price is relatively high for a simple cable with two magnets, and motivation to improve (not the specific direction of the plug was criticism since day one of the delivery) is also available.
So strong buy recommendation because there are no alternatives. The critical points for me, mechanical relief of the USB connector and higher charging current, have been met.
