buttons: tactical feedback weird...

so, i know this is pretty subjective, but what are people's general opinion of the buttons on the 945LTE?

my unit arrived today, and I'm finding them a bit meh. and nothing like i've experienced on my 935. the best way i can describe the buttons on the 945LTE as a bit "rattle-y" when i push move them, they give me feedback and work but it feels like they don't have a single click. it's almost like a semi-stick clickety-click feel.ie, there are multiple levels of "feedback/contact."

in comparison, when my 935 is performing at it's best, it gives a satisfying single click. when its at its worst, its a mushy push which doesn't offer any feedback.yet, it always works fine.

i'd love to hear if others are encountering this or there is a lot of unit to unit variability.

thanks!
