Although the unit came in a huge large box, but is really very handy and also pleasant in weight. There is a German short instructions, that I have not yet used. Detailed instructions there as a PDF on CD. Who has but need for this device a manual probably a problem with a toaster, because the operation is really simple and very intuitive.
The display is for the range of functions absolutely fine, the backlight is bright, you can read everything. Pixel or not, you got along everywhere and I despite the low resolution never felt restricted.
The reception is amazingly good, I get almost always receive on all currently visible Satellite. The connection to an EGNOS satellites, however, always takes a few minutes. Perhaps the correction data is also not so often transmitted and therefore it takes a little bit.
The precission is amazing. Even without correction signals from EGNOS is true in 90% of all measurements the position to the nearest meter, if you moved you can even follow closely in Google Earth exactly where you have to move along on the sidewalk.
The only problem of the unit: It's no cable here. This must be purchased separately for 30 euros, to come again 5/6 euros for a USB-COM adapter, if you have a newer computer without COM port.
But even with extra cables the value for money is very good. -> Unlimited buy recommendation
