I immediately thought of a non-medical use case.
A pregnancy and birth in Singapore costs $5-20k, so an extra $2k is not that much to be able to see your baby move and grow whenever you like as opposed to having to wait for your monthly appointment (and perhaps post photos on Instagram). It's a bit much for me but I might have bought one for $100.
Some redditors working in US ER departments complained of mothers turning up with "complications" mid-pregnancy because of the mandatory ultrasound that follows, allowing them to see their child, at which point their symptoms mysteriously vanish and they head home smiling.
