As an instructor for over 35 years, I've learned that swing aids are only as good as your students will use the aid. And a swing aid has to be able to fit in the golf bag, be easily set up and put away, and easy to use. Swingzy is all that and more. There's an obvious use but secondary uses as well, making this a new "go to" swing aid with me and my instructors.

Very good inexpensive training aid. Effective if used regularly

All good!

Makes you swing from the inside
