For those on the fence about the Darblet, I just want to share my experience. I've been using the Darblet with my HD33 since September 2012, and just recently starting have issues with the device (no video was being displayed). I worked with the DarbeeVision team to triage the issue, but unfortunately we couldn't resolve the issue with our troubleshooting. Although my device was well out of warranty, the team had me ship them the unit for replacement. I'm back up and running again and couldn't be happier with the service they provided without any obligation. It's a great little device, and you can be assured the team at DarbeeVision will stand behind their products.
