I have one and like it.
Currently run it through Sparrow mostly though.

How's ease of use?
It's pretty good. The little nub to select letters and pins and single button aren't too awful, and you can enter seed words right on the device. It's just a little fidgety at first getting used to it.
The screen is a little small so the software such as their Green wallet to connect to displays everything. But everything verifies on the device screen.
I only use Sparrow because of my amateur node set up. But Blockstream Green is a nice interface.
I'm no expert though. So. Im not shilling. Still want to get on the Coldcard train.
Cool I just downloaded Green on mobile to try out liquid. I'm glad there's easy options for desktop (sparrow) and green (mobile)
So far Green seems like a good interface

You canβt use your Jade air gapped with the green app (not yet).
BlueWallet or sparrow are nice to use for air gapped functions. I look forward to use air gapped function on green because the interface is so great
What do you mean?
If you want to use your Jade air gapped (no usb or Bluetooth connection) you have to use another wallet than blockstreams green. Itβs not yet possible on that but itβs coming they said
If you can connect a jade to green, You should be able to do air gap since it has a camera. Weird if that is the case.
Maybe Iβm being stupid but how can it be fully air gapped when you only can connect with USB or Bluetooth with Green? Not compatible with QR to connect 
Of course they can display QR codes. π ?
Yes but you first have to connect with USB or Bluetoothβ¦
After that, yes you can use the camera but that doesnβt mean itβs airgapped. Itβs the connection.
