I've waited for the updated, "pro" version for several years and bought it as soon as possible.
The first impression was disappointing, as the device made a lot of cracking noises when held in the hand, due to the battery block being loosely covered. Adding more rubber foam under the cover helped a bit. The overall feeling is still quite too plastic for this price.
Regarding the sound quality, I'm also quite surprised to get a constant, shallow hum with both internal and external microphones. RX Noise reducers helped to get usable results, but I expected it to be better. For the sensitive tracks, I'll still use my RME in the studio.
Maybe I've just expected too much from the next-gen converters, while it's still just a portable field recorder.
