5/5Overall a great phone. Looks really good for a refurbished unit, no chips or cracks. The only small issue is it was advertised as a dual sim but the tray only has 1 sim slot otherwise no problems.

5/5I'm delighted with the quality of the phone. I did upgrade from an A5 which was getting a bit slow but for me, as someone who just needs a phone to do the basics well and be quick doing it, it's absolutely perfect. Camera and picture quality is more than good enough for what i use it for. Battery life is easy 2 days with low to normal useage.
