I have got that baby/the WIFI/ but have not given it much use. Its a quality product and has surprisingly good feel in the hand.

The WIFI works flawlessly. The pendant is great but you need to spend some time to adjust this and that

Once you install it it can mess with a custom mach3 screen and change some buttons shortkeys, so maybe you would need to fiddle a bit with it. I have MachStdMill screen and still have not got the time to play around with it and see if it messes with that screen.

Hope that helps
