Mi flora 2017 vs. 2018

Hi,

I’d like to get a Mi flora plant sensor.

On aliexpress you can get a 2017 and a 2018 model. The sellers don’t tell the difference in their product description. One only says that there is a new package design.
2017 model is arrount 13$. 2018 arrount 23$
Both models say “international version”.

So is there any difference but the price?
Does someone here have both models?

Thanks
