Long story short, the 5-cu.-ft. Samsung WA50M7450AW isn't worth your money. We spent a week testing it in our laundry labs, the WA7450 did not deliver clean laundry in a timely manner.
Why you should pass
During testing, we had tons of issues with load balance. On almost every cycle (even Spin Only), the WA7450 would stall out, filling and draining over and over again. We ended up waiting for two hours for a Normal cycle to finish, more than double the estimated 56 minutes.
