M8 with 2GB ram for £60 or MX3 for £90? Whats the difference?

M8 with 2GB ram for £60 or MX3 for £90? Whats the difference?

Hi All,

I am trying to choose between the M8 with these specs:

CPU: ARM Quad core Cortex-A9r4, 2.0 GHz
GPU: Octa-core Mali-450MP GPU 600MHz
RAM: 2GB DDR3

Nand Flash: 8GB

OS: Android Kit Kat 4.4

Or the MX3 with the same specs but 1GB less ram.
The M8 is going to be about 60-65 quid and the MX3 would set me back about £70.

My question is are these machines pretty much identical? I spoke to one of the sellers and he says he stopped selling the M8 as the build quality was poor compared to the MX3 and the extra GB of ram made no difference? Also i was told and air mouse is a pointless purchase as it has to be recalibrated every time you turn off the box, is this true?
I'm *very* tech savvy but new to android boxes, so any assistance would be appreciated!

Thanks!

1.) Yes, he is right (also bad hw quality)
2.) No, he is wrong (especially at Android).... Take a MXIII 2GB and you will also have the better support also here at the forum because you can also use every custom rom for the round devices
