Rated 1 out of 5 by from Appauling My dad bought this phone for me less than a year ago. He told me it wasn't the most expensive, and I accepted that. I was just happy I was getting a half decent phone. A year on I'm now thinking about replacing it. It came with its own case and screen protector, the case I still have, which I will admit is handy, I can store thing in it, and the fact that it's clear means that I can decorate it with bits of paper and thing. However I had to stop using the screen protector, because it had scratched within a few weeks of being at school, to the point I was struggling to work with it. My phone then worked fine, apart from the fact that it cracked really easily, until recently. The battery life has now gone from amazing, to really bad, I can no longer use it for a day, even just using it for 10 minutes and it can lose over 10% battery. On top of that, my keyboard stopped functioning, so I can no longer sign into things, send emails or texts, because I can barely type out simple words.

Rated 1 out of 5 by from Great looks, but... OK, maybe I expected too much. For the cost of half a tank of petrol, this phone looked a good TEMPORARY replacement after I managed to put my iPhone SE in a load of laundry and then the washing machine! It's a goner and boy, you miss 'em. So while the insurance process started I bought this. I have had an Android phone before and boy, this phone is slow. It eats battery life and constantly buzzes and makes other noises which I’m sure could be switched off if I could figure it out. It doesn't even pick up a signal in my house so doesn't qualify as a phone!! An iPhone is like most things Apple, logical and easy to use. This is clunky, badly designed - the on/off button is just where a right handed person holds the phone - and I can only presume it's aimed at kids judging by the number of times I get asked to play soon as the new iPhone arrives life will return to normality and this bit of cheap tat will go to the back of a drawer somewhere. Sorry to be harsh but not for me...
