Just received this today as a gift, and based off first use, it's amazing!! It says it reaches optimal performance after 7-10 uses, but it's outstanding just after the first use alone!
I recently was gifted the Y2, & I absolutely love it. I am on my feet constantly for work & my feet just kill me ag the end of the day. This is changed my life completely!
My husband and I bought this because my feet ache a lot and he has neuropathy. We both enjoy the massage and my husband feels like it might be helping the neuropathy a bit already. We've only been using it a week so far.
