User opinions and reviews

It's almost perfect. Just a size matter:)

It's tiring if you're a woman or someone weak. This is a rugged phone for people that work and need the protection on site. Switch to a iphone or something light that you can handle.

450 grams get tiring very quickly. I have the older model and I find it annoying.
