Working very well as an SDR receiver for the NOAA weather satellites in conjunction with my homemade quadrifilar antenna, recommended.

My first impression was not great: the PCB in the enclosure rattled back and forth. I took it apart to add some non-conductive material to pad it so it would be a bit more sturdy. My next big gripe with this model is it does NOT tune down to 500KHz as advertised. An upconverter is required if you want to receive any signal below ~25MHz roughly. Had it actually done so, this would have been a great value unit, but as-is there are much better quality units on the market at this price point.

Very disappointed! If you have a soldering iron and knowledge in electronics you may buy it. Very low sensitivity and more than 63 ppm frequency inaccuracy. After (re-)soldering important connections, which were partially not soldered at all, the sensitivity has improved and is comparable to similar devices. It is now usable, but the frequency is still more than 40 ppm wrong. It's far away from the promised 0.5 ppm in the specs.
