Nice features, but 5hrs wash/dry cycle!

Decided to buy a washer/dryer instead of 2 separate machines, going for Samsung top of the range with efficiency, speed + no lint screen nor extractor. The experience hasn't been great - wash time around 3 hrs and drying cycle for 5kg of shirts and underwear took well over 2hrs and never comes out extra dry but damp. Samsung admitted a WD on dry doesn't do 100% dry. Be wary before purchasing!
