I have bought Asus memopad HD7.It did not feel satisfactionary with that.Simply it becomes hang.It always gets problems.It also has less service centres.Its camera is also not good.Everything in it is a problem.But its battery capacity is good.Many times I have faced many problems with this tab.Not worth for money.It takes more time to charge.In my view it is worst tab.Its build quality also not good.Once it gets problem, then it gets many problems quiet often.It does not have any sim option.
