This product helps me with my form and to develop power. I haven't tried it with the 8lb band because the 5 lb is enough for now. I would definitely recommend watching some of the Youtube videos before buying the product as well as using them to train.

This thing is great. Some resistance for strength and a training tool to help with form. Listen to the pros and you'll learn that proper form will add distance which will remove strokes.

I bought this as kinda a joke to annoy my girlfriend and make her laugh at me for "training" to throw a piece of plastic. Little did i know this is no joke, it has actually has helped me a lot by correcting my throwing motion. I pick it up and use it when i get board just sitting in the house and it really builds arm speed and it helps you find a good release point. I cant believe i am even writing this review ( i feel like a jamoke on TV telling you how great the Sham Wow is). but this is a great product and if you are interested in this at all i would buy it, because i love it.

This training system is pretty dope. It pretty genius. The resistance bands are great for building arm speed. I used this 2 times and have noticed a major difference. This system has helped me with my form and helping the disc close to my body on release. The Co thing is you can also add more resistance bands to it of you have them. I had a pretty weak forearm and with this system it's helped my a lot, keep in mind I've used it twice, I went onto the course and my form and power with sidearm is pretty decent I'm a lot more confident with throwing sidearm. I can now hit around 320-350 consistently now with sidearm. All I have to say is get this product. It's great.
