I use one and it is a cracking device and the stat tracking is great only one issue really, the following statement from Callaway;
Important Notice about your uPro Product

Callaway Golf will continue to honor the limited warranties for all upro devices.
More FAQ for your device:
• Shot Tracking is permanently inoperable.
• No new course updates will be processed.
• The upro, upro go, upro mx and upro mx+ are not compatible with Windows 8.
To be honest I did not know about this until I got mine so a bit gutted but then again I paid £55 for it so quite happy really.
The device it's self is quite good and accurate, they do have one hole wrong on one of my courses and it will not be updated.
I got mine more for the stat tracking which is second to none and the website is very good but this will all go at the end of the year, I do think this is a real same and a bit cheap from Callaway, they happily sold the products worldwide then just decided we don't want to do that now give it a year and we will shut it down.
The old ones do get very bad reviews and appear to of had quite a few problems state side so I guess this may be part of the reason.
