Of course, it's our only connection with the club, and depending on how we do it it will influence the shot in some way.

I'm not going to teach you how to hold the golf club today - I'll leave that to your PGA professional. And of course Power Tee are an official supplier to the PGA, so that gives you an idea of how highly respected the product is.

The way you can use it to make sure you get the golf grip right is that once you are happy you've got your hands on the club the way you've been taught to do it, you can set up to the golf ball and play your shot. I would recommend that when you're learning the golf grip, start off with fairly gentle shots. 

If you're happy that the shot is as you want, and you're happy that your hands feel good and they've stayed in position, the Power Tee is doing the job of getting the next ball ready. You don't have to take your hands off - now you've got the added advantage of being able to go ahead and take the next shot without changing your hand position. That means that now you're learning to hit good shots with the correct grip in succession. 

What I would say is don't do more than three at a time, because there's every chance your hands will have slipped - at that point reset your hands on the golf club the way you've been taught, and then go ahead and hit another three.
