The Hauwei CPE Pro 2 5G routers are actually readily available from CEX from people who for some reason were able to keep theirs. There seems to be some confusion about if you keep it at the end or not now and if you are charged a fee or not for doing so.
For £210 they're a steal compared to how much they're going for brand new lately. I ordered a B Grade but seemed to send an A as it was boxed complete in better condition than the unlocked one I bought from Amazon, as I seem to have scuffed it moving it around.
