I received mine from Amazon a couple of days ago and love it! The only thing that bugged me a little was the tiny artifacts from the marker. I got brave and upgraded the firmware to the February release and now it's perfect! I purchased various SMA adapters and have been putting it to use. As a Amateur Radio Operator, this is hands down the best thing outside a radio and antenna I have ever purchased! It's got me pulling all my old antenna books off the shelf and re-studying everything. Mine also connected without issue to the Windows 10 64bit software and to the Android phone program...
