They seem to be working fine. I haven't looked at their tech yet to see if the + actually has the best portability, or if they're properly calibrated (they're sold as being made for Stratux). My complaints are as follows: One came with a broken case. I guess it doesn't matter as it allowed me to see how to remove the case from the other. You are very hot. This also causes the connectors and the USB port to get very hot. For example, in the style of "burn your finger". So far they seem to be working but I'm just overwhelmed by the heat. Any part that gets that warm should have some sort of mini aluminum or copper thermal synchro installed. The heat worries me they won't last too long but time will tell. Overall, this was the best value I found for a Stratux. You can get antennas and similar SDRs for the Stratux but they don't use the best components that are said to help with temperature fluctuations so I think this is the best kit and not really cheaper.
