All of our neighbors with large dogs have this product, I finally caved and I'm glad I did! I have a 6 month old Golden Retriever and I was able to run him quickly since I was able to throw so much further. We will be buying again. Great price too, same product at my local Walmart is $11. The tennis ball it comes with has a great bounce, I don't plan on letting my dog keep the ball when we aren't using the launcher, I'm sure he would shred it quickly!
