Query: neither the 890 nor the "support" worked for me

If the 890 remote worked as promised (and as some people experience) I'm sure it would be great. But it didn't work for me. After loading the software, updating it, entering my units (all Sony), and downloading the info to the 890, i found the 890 would not control my receiver or tivo. After an hour of trying to figure it out i called Harmony tech support. Their guy couldn't get the 890 to take input from either my computer or the sony remote, so referred me to their level 2 support. After waiting a half hour for someone to pick up i was disconnected. I emailed tech support, but after 5 days i hadn't heard from them. That's all the hassle i'm willing to put up with, so sent the unit back to Amazon.Amazon, of course, is great about it all - quick response, no hassle, full credit. Gee, why can't harmony take a lesson from Amazon??
