And I'm thinking about giving any cheap one a try anytime soon, but only if shipping it down to my country Nigeria won't be expensive.
If you're just thinking of trying not because you need it for the long term, I'd suggest reading some reviews instead. Most of these things require KYC and I don't think giving up $5 for your details is worth it. You might want to check out privacy-focused debit cards, although most of them end up as a scam.
