I have 3 chuckits, two of the same 26M in different colors and one of the smaller size. I have had these for YEARS and they are still going strong. My 7 year old golden retriever is obsessed with catching tennis balls, and the chuckit makes is so much more fun for her (as I cannot throw very far). Whenever I get the chuckit out as we get ready for a walk she goes crazy jumping up and down and pawing at the end that holds the tennis ball. It is by far the best dog accessory I own,  I can't imagine not having one! If your dog loves fetch, don't hesitate, this thing is amazing!
