After about 2 weeks or so of use, the lid still takes 25 seconds to "soft close" when I push the lid about 30 degrees from vertical (so that it has about 60 degrees left to close).  It has a fair amount of resistance to push shut, if you want it to shut quicker.  This is not good for a family that has towels hanging near the toilet, and has read the studies about how much water sprays from a toilet, in micro form, when flushing.  We want the lid closed when flushing to keep toilet water micro-droplets from hitting the towels. My children, like most people would be, don't want to wait for it to close, nor put in the extra effort to force the lid shut, before they flush.  I'm hoping it loosens up a little over time.  Otherwise, it appears to be of solid construction, and fit my Toto round bowl just fine.
