No. This mastery tool doesn’t require assembly, set up, or special care. Simply put it on your club and start swinging! It’s portable, and so lightweight you won’t even feel it on your clubface.
If the velcro starts to come away from the strike shield just put a dab of glue between the velcro and the shield and press down and shield will be good as new. The need to do this is rare, however, we have had a three customers mention that this has happened. We are researching to see if it is due to the how the product is being transported or if the people using it are so forceful that they are literally knocking the cover off. If so, just smile😊 A little dab of glue will fix everything, but hopefully won’t be necessary.
