The uniden guys seem to have a good gun support. For a certain model of lidar gun, they used 3 different copies to form their entire algorithm which successfully jammed every single version of that lidar gun that our group owns.
They ran into an issue with only one single lidar when placed in a specific mode but since they had their engineers out to the testing event, they recorded the gun on the spot and the next update had it fixed. We really don't know how they'll handle this in the future but the rep is very responsive and the engineers fly out from Korea for every single one of our testing events since the r9 was released. A good sign so far. We also found a mechanical issue and brought it up to them and they had the part redesigned to fix it in a few months.
One thing I do want to touch on is we don't yet know what their warranty/replacement policy will be like. I don't think there's currently any way of getting replacement parts easily and we don't know how much it will cost.
Finally, the r9 is not currently standalone. If you just want the laser shifters without the radar part, that's not possible to purchase (although we have tested using the laser part with a dash mount r4/r8 and it works perfectly fine). We're trying to convince them to sell the laser part separately from the radar...
