Query: Sloppy piece of engineering

A sloppy piece of engineering- The expansion module cover keeps slipping off, specially if you wear the Visor on a holster - The batteries drain like a leaky tap - The screen corners are poor - I changed the batteries, and lost ALL the data and new applications that I had! - The machine is thick and bulky - looks like it needs to go on a dietNet net: You would be better off with a pen and paper diary than this clunky piece of plastic! Welcome ye pretender!
