I have not received the cell phone as part of a test. As an outdoor phone that Thunder is ideal in my opinion. Drop tests it has passed - the display has kept. Also take a dip in the water it has survived without any problems. The operation itself is not comparable to a "normal" mobile phone. The battery and SIM card compartment is screwed and therefore not suitable for frequent switching maps. The camera is suitable for a maximum of snapshots. Once you try to photograph moving objects or persons, I have received only blurry photos. I think the phone is to call and the sporadic Internet browsing sufficient. Just who would be available on site or at other outdoor activities - and precisely for this smartphone is also thought so. Therefore, even the 3-star rating. Frequent users should opt for a more comfortable cell phone.
