FAQs: Q1: The nozzle doesn't fit, I can't use the pump. A: The inserted white plug (air stopper) on the ball must be removed first! Inflation Instruction: Step 1: Take out the inserted white plug (air stopper) from the ball.Step 2: Insert the tip of the pump into the mouth (built-in variable aperture).Step 3: Pumping the ball to proper size (usually 10 minutes for a 75cm ball). Step 4: Quickly replace the white plug back into the hole to stop air leak. Done and Enjoy! Q2: Ball size is smaller than advertised.A: Ball is made of rubber which will become much contracted being packed tightly into the box. Thus, keep pumping to stretch the rubber is the key. If it is hard to reach suggested ball size during 1st inflation, users can leave the ball as it is for a day, and then pump again after the PVC material gets fully stretched. 60-Day Money Back & 1 Year WarrantyIf you are not happy within 60 days we will refund or replace the product.
