Is it safe to buy a refurbished unit online?

Many 3rd party retailers offer refurbished models for sale, often at an enticing discount. It can be very tempting to assume you're getting a great deal.

However, many of these are actually scam websites selling unregulated forgeries, liable to fail moments after they're unboxed. Frequently they seem to do nothing when pushed.

The only way to be sure you're getting a genuine Normal Button is to purchase one directly.
