Such a terrible company.The products I got are crap; My tablet was laggy and It wouldnt work properly, even if I did everything I could to get it to work properly, nothing happened. Then a week later it broke. I have a Sheffield boom speaker and guess what? it skips. It jumps even though its blue tooth and it autimatically changes volume. Then I got a cellphone from sheffield, again its crap.I buy MB data and even when its on and available, it keeps telling me there is no service. I suggest you up your game sheffield because I am very fed up with the fact that almost shefflied product is trash, let alone they only last for a month.Im sorry to give such a bad reveiw, but seriously its useless.
