We bought this dishwasher to replace the one that came with our house. Our old one didn’t really clean that well and we had to run it every single day since we couldn’t fit much into it. Our new Samsung Stormwash 48dBA cleans really well. We only have to run it every 3-4 days now since it can fit so many items. The third shelf is extremely useful for washing silverware. Since we can remove the silverware baskets from the bottom we can fit so many more dishes. 
This Samsung dishwasher is very quiet. I always forget that it’s running since I don’t even hear it. I love how my dishes come out so clean and spotless. Even baked on stains comes off of the dishes after one wash. Overall this was a great purchase and I highly recommend this dishwasher.
