To be honest, I dislike having the machines in my saves. I find the game play very irritating. I occasionally put them in for gallery builds and the play testing drives me batty (you test a shower and the hamper fills up and now you have to do laundry. You test a tub, same thing. You didn't pay attention and your sim is getting in their pjs? Now you have laundry. Pretty soon you've got piles of laundry everywhere that need to be done before you can upload the lot).
I do have the tub and washing line in an off the grid lot I play periodically.
The build/buy objects, though, those are outstanding. They fit in a lot of different style builds--those rugs alone are awesome. I love the little side table and I love some of the wicker furniture. The single light bulb is a personal favorite and the sinks are fantastic. The clutter objects are great. I use this pack all of the time.
It's easily my favorite stuff pack for build/buy.
