Yea, I'm a URC user and have stuck with them for several years but the 990 doesn't look like anything special. Currently using MX-880's and some feedback on poor button quality is starting to get back. I have several iFixit kits with all the spuds and pullers you need, but wondering if opening it up and doing a nice clean will really make a difference. I'm so mad the menu/guide/info and exit buttons aren't larger. Lots of open space on that remote because of the small buttons. Really, is the build and button quality good on the 990? Worth to switch out some MX-880's to that model?
