This is the cheapest that I've seen the P2, even cheaper than previous deals.
Note that LuBlueLu-Store on eBay has confirmed that this is a maximum 45kPa version of the P2 even though LuBlueLu.com has it listed at maximum 14kPa.
I've ordered 2, I'll report back once they arrive about how they compare to my Xiaomi Viomi A9 which was rated at 23kPa.
Bad deal
