WHEN I OPENED THE BOX, IT WASN'T SATISFACTORY, SO I SENT THEIR PRODUCT BACK & THEY RECEIVED IT & I SUPPOSE TO GET MY REFUND, BUT ONLY GOT PART, I CALLED & THEY SAID I HAD TO PAY FOR SHIPPING & HANDLING. I ALREADY PAID SHIPPING & HANDLING, PLUS TRACKING FEE. SO THEY DIDN'T NEED TO KEEP MY $20.00 DOLLARS. BECAUSE I HAD ALREADY PAID AT THE POST OFFICE.
