I have 2" spacers on mine and have had them about a year or so. When first installed, I had to regularly check them and many times retighten them up, actually right now I only have the spacers up front because one of the rear had loosened and I didn't catch it in time, it stripped the threads on my wheel studs and trying to get the lug nut off of it, I cracked it in half so I just took off the rear and left the fronts on. The fronts have settled in and I don't have to check it as much and when I do they and no longer loosening up. So, do I like them? Yes and no. Seems once they settle in and don't loosen anymore they are fine but, can be hassling until then.
