I use it a lot, I like the build/buy and I like my sims to have washing machines and dryers.
The dryer sometimes lights on fire but if you clean the filter before using it you should be fine. Also it can be updated to be fireproof.
The only thing I find annoying is if you don’t take the clothes out of the washer or dryer right when it’s done, they start getting dirty again, which is realistic for the washer, if you leave your laundry in a washer for too long it stinks, but I don’t get it when it comes to the dryer, once your laundry is dry it shouldn’t start becoming dirty again!
