Re: Reduce odds of Item breaking and Randomize it more
@ID-Christian if you have a Sim with high Handiness Skill they can upgrade many items and make them more reliable, including the Sprinklers. I agree they break way too often.
I've just been talking about this on another thread but if you have Get to Work you could sell upgraded items in a retail store. I'm unsure as to which items you can do this with, I'm going to be testing it myself soon.
Or you could upgrade some items and save them to your library.
