DO YOU RECOMMEND ANY PARTICULAR TABLETS TO RUN MECH5?

SHIELD TABLET K1: 

We rate their performance highly and it is an impressive specification for only £169 (FEB 2017). 

Where can I buy one?

NOTE: On some tablets, due to the smaller screen and resolution the 'Burger Button' has to be used. For best use of MECH5, a large screen size and resolution is required. The Shield K1 tablet meets these MECH5 requirements so the 'Burger Button' is not required.
