EMS_QS versus Beddit 3?

I am super excited to start tracking my sleep and wondering which of these devices I should try. I have an Apple Watch and would want to bring data into Health App if possible. Having said that EMS_QS seems like the better selection. My mattress at home is very thick and that makes me wonder if the sensor underneath the mattress will work well…

Also I travel frequently and would like to bring the device with me…

Both devices seem like too much of a hassle to use when traveling, but if you must, the Beddit 3 will work better as it isn’t adhesive, and uses a a Bluetooth connection to your phone rather that WiFi. Also, the Emfit QS doesn’t integrate with Apple Health.
