I haven't been in here in a while and just skimmed to get caught up.
use a wooden skewer on the bowl to clean, not metal! I started using a small eyeglasses screwdriver to get into the corner once and it felt like I was scraping thin glass...I never did it again. I think it would be quite easy to scratch through it and expose the ceramic.
The clasp looks like a good idea. It seems to close the gap just enough to keep it airtight, from the pics posted on the web. I also was afraid some numbnuts would grab it and spin the bottom too far and break it, but the clasp will stop that from happening. I'm sure they don't like the little bit sticking out, but it's pretty small.
I, for one, am happy for the delay. I think this thing needs some tweaking after having it over time. My battery drains to dead after a week of sitting in the drawer, and I know they are aware of this problem...maybe even fixed it already, I don't know. I've also had three occurrences of what appeared to be programming issues, but DV thinks it might be the buttons, which they have already changed as well. So...they may have gotten some real issues worked out here before initial release.
