eufy Entry Sensor E20（20 Pack)

Sensors are probably great, Eufy ordering systems not so much.

Sensors are probably great but when trying to cancel the order before it shipped, it was impossible. Eufy’s sales systems send order to the warehouse almost immediately. Try and cancel online an hour after placing it, error code. Email support, 20+ hours to get a response. Live chat tells you tha once it’s sent to warehouse, that’s it. My order didn’t ship for 4 more days, their systems have 1 way limited communication. They sent it to me, had to flag FedEx to not deliver, it had to go back to warehouse, get inspected for damage, then another 3-5 days to process a refund. These 20 sensors can all send and receive with the home base while the home base is doing the same with multiple cameras. Their products are more advanced that their sales/shipping systems.
