I bought one a few weeks ago. Pretty pleased so far.
I can confirm that it survives being dropped onto a tarmac apron from 5 feet...
Battery charge using its cradle takes 4 hours. You aren't supposed to re-charge till the battery is low, so after initial charge I must have had it scanning for at least 16 hours, with the last couple of hours outputting Glasgow's ATIS, screen backlight turned on and "battery saver" turned off to try and run the battery down.
I live about 5 miles and slightly above Glasgow airport, although there are some buildings in the way. I am able to pick up all transmissions sitting in my lounge, including ground ops, Localiser and VOR. I can pickup aircraft on approach from when they join the frequency, at least 10 miles away. This is much better than a borrowed ICOM I had for a while.
In the air I was able to pickup VORs when line of sight - furthest I was away from any was 20 miles (with no issues) using its own antennae. No problems tracking using the information on the screen.
The speaker is pretty loud, although would need to wire it into a headset to be able to ident something in the air.
Haven't checked the glide slope.
Screen is bright and clear.
UI isn't entirely intuitive. Some things are easy (entering frequencies direct - there is a dedicated comm key to get you straight back to that front screen), some are a bit awkward. Saving and naming channels really should be done from the downloadable PC software as it is nasty on the device (which I installed with no issues on Windows 10). Once you install the new firmware, you group memories, then select which memory group you want to show on the front screen. You can then scan only this memory group (rather than the whole frequency band).
You can do "Dual Watch" but only to a single channel. Same with "Split Channel". You have to specify both of them in an admin screen. Makes them pretty much useless. Selecting a VOR radial isn't that obvious - takes a button press or two more than expected.
Build quality (as I say) feels great. Slightly awkward trying to remove the antenna once attached - you have to know where exactly to squeeze it. It is water resistant only if you don't plug in a headset.
Tried to buy a "listen only" ear piece to use when wanting to listen in at airshows etc but the after market one I bought on ebay caused it to continuously transmit (bad idea), as did the mono adapter I tried. I could get it to work if I pulled the 3.5mm jack out a tiny bit but that wouldn't be safe for any length of time. Another adapter had an end that was a tiny bit too thick, so it couldn't be pushed fully into the device (the 3.5mm socket is recessed). Means I've ended up using the bundled headset adapter and adding a 3.5mm adapter to the headphone socket to use with normal headphones. If you're only wanting a scanner - might be better to just get a scanner!
Anyway - that's my experience so far. Haven't had an excuse to transmit with it yet so can't comment on its clarity/ transmit range.
