■ The catch — co-equal billing, always
You'll refill it, and hear it. The smaller reservoir needs topping up more often than premium rivals, the pump is audibly louder than the Eight Sleep at night, and all smart control is app-only — there's no screen on the tower.
Dealbreaker? Runner-up №1 skips water entirely — nothing to refill ↓

The subscription tax
The Eight Sleep Pod gates sleep tracking, alarms and its AI behind a mandatory $199-299/yr Autopilot plan — skip it and you've bought a manual heater/cooler. Chilipad, BedJet, Perfectly Snug and HydroSnooze charge no mandatory fee.
Air can't beat the room
Air systems (BedJet, BedFan) blow ambient room air and cannot cool below room temperature — BedJet won't help in a bedroom over 78°F without AC. Only water systems hold a sub-room-temp surface all night.
Water means upkeep
Water units run a control tower with a reservoir you refill every 1-4 weeks, plus periodic cleaning to prevent buildup — and dual-zone (the config most couples need) costs roughly double single-zone.
