I'm looking for advice from people who are familiar with the internals of the Siig Minitouch. I purchased one on ebay and it arrived today, but the 3, e, d, c and space keys don't work. My options are to return it or try to fix it, but I'd rather not even try to repair it if this is indicative of worse or growing problems with the keyboard. Since the keys are all on one column, it seems like there's probably a short or disconnect, but would that be something that's fairly easy to diagnose and fix, or would I be better off returning it for a refund? My main concern is long term reliability, as I've been using the same unicomp keyboard for 11 years and ideally I'd like to have the same kind of lifespan on everything (though I know that's not always realistic.)
