It is very space efficient and convenient to use. I love that I can use both of them at once. However, I tried ending the load while it was still on the spin cycle (so I could transfer it to the dryer before leaving for the day), and it never unlocked for me, it just stopped spinning and stayed locked and I couldn't get my clothes out. So I had to leave my wet clothes in the washer for the entire day until I arrived home again. Also this is very minor, I wish that it had a default setting for drying so I would not have to choose a setting every single time except for special loads. I just want to press the button and be done.
