From the exterior, the phone looks very nice, observe to trust you the covers for the SIM card, SD card and headphones on the first glance that the unit is waterproof. However, I have tested this involuntary and can determine it holds in this respect its promises. One criticism is for me the layout of the buttons, which are attached nearly centered on the sides, as I sometimes do not exactly look there when you turn and thus the wrong button on the opposite side use that lets you turn on the LED lamp. Speaker and microphone work very well. The GPS receiver is excellent, I had no phone with GPS receiver that so many satellites tracked in good quality compared with App Satellite check). The instrument is liquid, the camera is useful, I use this mainly to work for documentation purposes, those who want more, is better off with the classic camera. Much criticism is Android 4.4 Kitkat. This Android version, most programs can not write to SD card. The phone has 8GB of internal Spreicher, of the approximately 5GB can be used for programs. I've been using the device for both road navigation as well as for outdoor navigation. Since the 5 GB are not a lot, I must already think about what cards I need and what I can just delete it. Actually was here 5 Android is the right solution, I hope it will someday give an update
