The only real gripe I have about the design is the a-bit-too-small size of the touch screen buttons. Overall, it has a feeling of quality, something that I appreciate in my expensive purchases. The lower scroll button on the face is also within easy reach of the thumb. It is likely better suited to right hand operation as the two side buttons are located where the right thumb naturally rests. The unit stays put in your palm as you access the three buttons and touch screen. The material on the back of the unit is a nice feeling plastic-rubber compound (plubber?).

You can see in the photos how the size compares to my вЂњold schoolвЂќ iPhone 4S (pictured below). The overall size is right around palm-sized. YouвЂ™ve got a battle ahead.ДЄesthetically, this is a slick looking unit. ThatвЂ™s a pretty tall order for any product, but especially for a product in a category (dedicated GPS) that already faces potentially fatal competition from the smart phone/app market. Due to the face-plant of the previous unit, this upro not only had to be good, but it had to make people forget about what happened with the previous upro. So you see, when Callaway released the upro mx+ earlier this year, it was more than just a release of the latest generation of the unit. You can see the original MGS forum post HERE. The problems with the unit were so serious that Callaway recalled them, issuing refund checks to those who returned the second-generation units. That stuck apple would probably prove fatal, just like the serious issues with the upro mx. More like getting an apple stuck in your windpipe. Instead, the issues with the previous upro mx were a trifle more severe. WeвЂ™re not talking minor issues, like how I sometimes forget good nutrition and eat an apple fritter. Some of you may remember from about a year ago that the last incarnation of the Callaway upro mx GPS unit had some technical issues. (Written By: GolfSpy Dave) I need to start this review with something that Callaway would likely rather I not bring up again.
