This is the best phone I have ever had (and I had a lot!!!!). It lasts on all trips in all hits and the battery carries for ever. But most importantly it's the size: Not too small so you can't read but fits easily in the palm of your hand and pocket. Excellent value for a reasonable amount
I have this phone now over 2 year and I use it daily. This is how a proper, functional phone should be and look like. Battery life still is 2 days with normal use. The only sign of ware is the alu backstrip is a little loose, but that's really nothing to be bothered with
I honestly don't understand why there are only 10 reviews. I'm about to buy another one, just in case they stop producing it in the near future because there is no equal one available that is rugged, waterproof, small ( I had also the atom 2.4inch, but it's just to small for daily use)and ok performance. Keep it going uniherz!
The nec Nothing to say it's perfect I already have the little Atom and the Titan this one is me ideal compromise.
