Review: It's not the smart phone......It's understandable smart phone - Battery life is amazing. When it was new it lasted me for 6 days+ After 6 Months battery tend to last for 4 to 5 days on dimmed display and internet on. I work in cold environments often I have to go to a chiller that is at 10 degrees then move into the freezer were is -12 and once a while into the BLAST FREEZER where is whooping minus 30 degrees. And then I have to go back to the office while in cold days my boss turns the heating to the maximum. The phone doesn't have a problem with the temperature fluctuations. I tend to keep my phone alongside with my keys. and there aren't any displeasing scratches on the screen. Once at tea time, I decided to show my colleges that I have a resilient phone and then I have thrown across the road. And few scratches on the rubber around the phone, and the screen if it could communicate it wood laugh and shall ask for one more throw. Music plays well on the phone and watching youtube is decent. The only con of this phone is sooo slow, you cant have multiplay apps runi9ng in the background. But the phone is designed for working adult not teenagers. And the GPS in the phone has never let me down.
Review: Don't buy - What a load of rubbish. Once I charged the battery and setup the phone it crashed and now will not work at all and can't get anywhere with customer service. And the £200 price tag is definitely a con shame really I was really looking forward to using it as mine had so many problems.

### ⭐⭐⭐⭐ Robust smartphone for physically active work and play
*by K***N on 16 October 2018*

This is a great phone for anyone who works outdoors or with machinery and particularly if you wear gloves while working, or if you're physically active outdoors. It's more robust than normal smartphones with a tough screen and a good grip from the casing. Set up was fairly easy although a word of warning: I didn't choose the language quickly enough initially and had to find my way out of the set up in Korean (I think!). This wasn't hard but it was a little frustrating to work out how to get back to the start menu. Once there, the set up second time around was painless and straightforward. The phone itself is great and I've had no problems with using it at all. Ideally, I'd like it to have come with a slighter bigger screen but this does the job for now, and the camera and display work well for me and are both an improvement on my previous phone.
