my middle ring started to pop out on the top, but the bottom is still snapped on strong.. it's a matter of time before it completely falls off.. but no worries, i'm going to take it back out and fix it tonight when i get home from work.. i'll snap it back into place and see if it holds any better.. if it starts falling again, i'll resort to some double-sided tape or some type of adhesive..
i just got mine and according to what Dave tells me, it's a newer design that should snap into place tighter and hopefully not need any kind of adhesive to keep it in place.. i'm wondering if i just didn't snap it down tight enough when i initially installed it.
