I can't understand why you didn't get response, is a good oportunity for someone who maybe is not going to use much, so doesn't want to spend money, and this way can have a useful tool. I replied as soon as I saw it, but perhaps because I am almost new to the forum, my posts need to be checked by a moderator before being published.
I have been thinking and probably is not a good idea in my case, I live in Spain and the shipment costs won't make it worth, I believe I can buy a no-brand one here for 10-15 € (7-10 pounds) and the costs involved sending it should be higher. Anyway, I know you didn't do this for getting one of those cheap products from Pimoroni, but send me your address by DM and I'll buy one. Such a good initiative as yours deserves some reward.
Regards.
