pl check in Giant stores in the first floor in Hyatt plaza. But sincerely speaking , in this part of the world, clothes get air/sundried quicker than the drier , for 6 months of the year and the rest of the month in 4 hrs .
A drier can need some outlet drain pipe/blower I suppose , so do u have the facility in your house to fit the same now or can it be made pl check with the owner, if you are in a rented house. Also , it takes a minimum of 80 minutes, to 100 min, to run the drier and get the clothes warm and dry to just remove and just fold the clothes. In all I advice not to go for it in Doha.
