When I did the research: Aranet4

I bought one for myself, fine, then two for my siblings. The two I bought them always measured about 100 apart, when right beside each other.

To say – use the measurements as a comparison of what you know.

I have this too and it's a lovely device. E-ink screen looks perfect, mine has lasted for months and I don't even think about the battery.
