Review title: Not Useful!!!
Product review: You real can't "hinge naturally" with this device. The hinge or the power angle should happen from the momentum of the backswing and pulling of the arms by your lower body movement on the downswing (compressed). Check out some videos of Sergio Garcia on YouTube to get the best understanding.All it maybe really good for is check your positions at very slow pace or pausing.If you need it for that do what I did and find a knock off version on eBay for about $3. This one by Swingyde is way over price. Otherwise I say do without it!
