i would advise people not to buy anything from this company which is based in china. i bought a dm7020si from them and it was faulty when i got it (it never worked ) it even has a rattle inside . they have a support line (which is never online )so your only options are leave a message or email them . i have tried and failed to get any help from them (i have been ignored ) if you are very very lucky and they send you an email (they say please stop contacting us we are not technical) you can foret about the 18 month guarantee they advertise . i have lost in the region of £250 so please be carefull buy local if you can (atleast then you have a guarantee and the law is on your side) better to pay a little extra and have peace of mind. i intend to post this on as many sites as i can and in the end they will have lost a lot more than me .i cant understand companies like this (if i was them i would want to have a good name) and sell more ,not have a bad name and sell less. word spreads very quick online ,they could have lost thousands before the day is out by the time i finish posting .
