This is a great deal I found on Costco.com for anyone that is a Costco member. It is the SKLZ Flex trainer and also comes with the Pro Rod set for 49.99 with free shipping. The Flex trainer is going for 71.99, that is the 48 inch version, which is the one you get from Costco, and the Pro Rod set that is going for 20.50 on Amazon. Costco is selling this for almost half price. I have used SKLZ products before, I was a coach for my son's baseball teams and daughters softball teams, and used their baseball and softball swing trainers for many years. This company sells really good products. This SKLZ Flex Trainer is equivalent to the Orange Whip Trainer which a few of my friends have, and the orange one goes for 109 dollars. I used the Flex Trainer today at the course, and loved it.
