This mattress cooler/heater is probably one of the best purchases I've made in a while. It has its quirks and used to have a lot of connectivity issues that have been mostly resolved.
At the time of purchase in 2022, the King-size pod 2 cover system was just under $2000.
Something to consider that I thought of after I posted this video, you want to be extra careful if you have pets that go on your bed. Sharp claws can pierce the little water grid and lead to a bad day. You may be able to get away with a thick cover over the Pod cover, it'll still transmit the temperatures (just take longer), but the sensors may not work as well.
