I haven't had the massager for long, but my early experience has been very positive. It fits my size 11 mens feet very well and can apply far more massage pressure than any "foot rub" I've ever had. I like it a lot so far.
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!
