The device is easy to handle, not bulky, not whimpering, reacts relatively quickly. The operation is a matter of habit, I can handle, some of clicking is cumbersome, on the air, on the MTB, but I need a few operating steps. Software is a kind of pop-up which will update the software in the device. It's good. Then comes, only Win Explorer, the online application. You can log in, register and look at maps / routes. Creating / editing favorites etc. does not work, call routes, go create itself, not even edit. Storing and synchronizing is with cloud stuff endlessly protracted, completely free enjoyment. The attachment is craft course primary school. Could only be getopt from tethering. On rough tape I have the construct or less fixed. But snapping / screwing appears to be safe. I pulled the cable tie on until I had been looking for the blendfreiste slope in sunlight. Works then, even when driving. If I (all adjustable) not overcharge the ads, I come as a wearer even with a neutral Sportbrille cope. Navigating is relatively accurate and not sluggish. Something I had to practice. Lasse I eg (MTB) streets, the part attracts me too much on this, it should avoid them, it makes me drive around the smallest village in the big bow. For unknown long distance would that make me crazy. With the options to see a wireless speedometer where I am justament and record the distance I was looking for that and a little more, doing the part. Much more comfortable and there is also determined, but not for 150th I regret nothing!
