Thanks all- as it happens, ive been feeling a bit rough today and thought it wise to do a test…. I have Covid and so will inform notability and Ohme that they are not allowed to attend tomorrow. I will seek to them about the charger too. They have sent me tow Ohme pro units…. no idea why- they are both the same. I think I will opt for an untethered unit and that will give me more flexibility. I don’t need the screen on the device as I have my phone.
