Bests & Worsts Reviews from Amazon

I bought this product only 4 months ago. I was very happy with the quality of the product, but it is now emitting sparks when I use it. I am a professional massage therapist and I am unable to use the product anymore because I am concerned with the safety of my clients. The return policy states it can not be returned after 90 days, therefore I can no longer use the massager and have lost all of my money. Although I liked the product, it is not worth the price if it will only last 4 months.
