Momentus Golf Power X Swing Trainer

My 6 year old daughter plays in a 9 hole par 3 course that has a short hole that is 98 yards. I have been measuring her drive every time we play on that hole using my Bushnell Pinseeker Laser Range finder. Her carry has been averaging about 85 yards. I waited 1 month before leaving a review so that I can get a 10 game average with this 30 gram weight installed.After 10 games her driving carry distance average has increased to 93 yards. With roll, she was able to get on the green in 1 with a 2 putt for a Par. Her score has improved by 3 strokes on the average.I take videos of her swing and where I notice the change is in her takeaway and the start of her downswing. Sometimes her takeaway is too fast and then transitions into her downswing too quickly. This really affects her power and distance. Her swing speed has gone up from 60 to 65 mph, with an occasional 70 mph.I have ordered 5 more of these to test with her, 3 and 5 fairway woods, and, 4 and 5 Hybrids. I will also try it on her putter. I will update this once we have tested them on those clubs.>>>>>>>>>UPDATE 3/31/2017<<<<<<<<<So it has been more than 3 years since I wrote my original review. My daughter has grown and she uses a Ping Ladies set already. Since staring the review, she won the Cobra Puma Junior World Championship. And yes, these were on all her clubs back then. When she switched to a Ladies set, she has kept it on her ENA Super Light Driver and her putter. The Iron of Ping are so easy to hit that she did not see the need. So what I did is I put it on my clubs, and I love them. It stopped me from hitting on the toe for some reason. Don't know why, but who cares, it worked for me!

Not a lot of difference.

seems to help as a counter weighht with the swing. I put it on my driver and have never taken it off. TEMPO!!!

Easy if over-priced way to back weight a driver and increase club head speed. Seems to hold firmly on a Winn Dri Tac grip... I would glue it if I felt otherwise. The USGA and R&A say you MUST glue it, but they are beyond silly with too many rules.

Very difficult to install into the grip. You can forget using it on the course with different clubs. Flew off my grip 3 times and the third time it was lost for good. I didn’t miss it but I do miss the $16 I spent on it

Works as describe

Perfect for an introduction into the back weighting concept. Interchangeable to all clubs. I would recommend for practice and play.

had no significant affect on my swing, distance or control.
