I purchased an 7 inch tablet quad core Ainol Numy3G AX1 last year from a company called Ebellking.
2 sim slots plus sd card slot, hdmi and usb ports gps enabled for just £84.
Its very very good,Ive just returned from a trip to Belgium where I used it as a very accurate sat nav.
I run it through a spare 21" monitor via the HDMI port to watch netflix etc with amazing clarity and the sound via the monitor speakers is good too, yet Ive never seen a mention of this make in reviews,is that because you only review samples sent to you ?
During the time Ive had it Ive also purchased and sold on a Sony Xperia tablet, a Motorola Xoom a blackberry playbook and an HP tablet,all found wanting .
The Numy is here to stay
And no,Ive no tie with the company,Im just happy with my purchase.
