My wife wanted a cheap Android to replace a broken within contract iPhone.
She originally bought an Alcatel Pop4 from Argos for £70 but it was dire as it only had 1GB RAM and 8GB Storage and that just doesn't work with Marshmallow from what we saw.
It just continually crashed due to out of memory and/or storage and we took it back - that was even with a 32GB memory card and moving apps to there.
I believe this phone should be a lot better as it has double the RAM and storage. It also has a 3000mAh battery. Processor is a Quad-Core 1.3MHz something-or-other.
Unlocked SIM Free
3G network (Advert actually says 4G so unsure)
Ultra-sharp 13 Megapixel rear camera 5 Megapixel selfie camera
5.0" IPS HD screen
Blazing fast quad core processor + 2GB of RAM
Android 6.0 Marshmallow OS
16GB Storage + 128GB SD Card Support
Dual SIM Support
Hope this is of use to some of you :)
Edited to add: Available in Gold, Black and White. Also available from Appliances Direct (same company?)
