I've had the 8811 for about 2 years. It's been great, but the down arrow button is starting to go (I sometimes have to press it really hard, or numerous times to get a response). So, I'm looking for a new remote for X-Mas.

How does the memory size of the Kameleon compare to that of the 8811? How many learned codes can I store?

I've read mixed reviews on the Kameleon's "motion sensor". Is it really as bad as some people say? (If I cough will it activate everytime?)

Finally, what do the people here think of the buttons? Are they completely flat or do they have little bumps that I'm not seeing in the photos?

Thanks.
