Very unique!
New user here! I really love the concept! Yes they should adjust sounds vibration etc. and have more explanation. I had the one which track sleep and I think it is more accurate than anything else I have tried (I always use Fitbit). Overall very promising, it is comfortable to sleep on, and the first time I tried I feel asleep right away!Features and levels are confusing
Hard to notice any real difference between relax and sleep functions. Then it hard to tell a difference between levels. Why are the levels even locked to begin with? Then the three position mode option, on the lowest setting, some notes are still too loud but if you lower the volume, the vibration lowers also.
