Full size washer and dryer stacked to save space. I found other stackables to be smaller - this is full size which is awesome! It also gets clothes super clean. Stains that had been set in for months came out the first time I washed them in this. Our water bill also decreased and we've been watering flowers more in the summer heat, so I can only assume this is a big part of it! So far, I'm thrilled! The only things that drives me crazy is having to wipe the rubber around the washer drawer to remove excess moisture and that I can't figure out how to download the waterproof cycle to wash mattress pads and bath mats with rubber backing - the app leaves A LOT to be desired.
