Item is returnable, but does not qualify for free returns.
This replacement to the Unique Fill-N-Drill comes attached to a strong rubber cord for easy installation so you can start training immediately.
This has been the best replacement ball/string I’ve found since my original 30ft thick rubber band string which I haven’t been able to find. I’ve tried several others and either the string type was not good or the balls went flat almost immediately.
Works very well
Very good.
This product is an extremely easy to use and beneficial training aid. Great for perfecting your timing of swings, as well as the overall skill level of your various swings. Good for foot work as well. Great exercise tool that I use often. The only problem for me is no court time, so this is what I use all the time. I pretty much have to order them in bulk because I wear them out so quickly! I would recommend this product for anyone who wants to work on their training off the court. Great product.
