Apologies for not replying sooner... work+real life etc etc
- I don't really use the BitHD Razor due to the somewhat annoying custom cable adapter (
it's too thin for a standard USB port) and having to use Bitpie wallet app.

Thick? It doesn't fit into a standard USB port? What kind of cable does the BitHD Razor use and how do you overcome this hurdle?
No, I meant the wallet itself is too thin to contain a standard USB port (and by "standard" I meant microUSB or USB-C)
The device really is quite thin:

It uses an adapter called the "blade", which you plug a MicroUSB cable into... it's just a bit fiddly and annoying.
