I have used many swing aids and this one is the best. There is no way to cheat when using this club. Not only does it increase your swing speed and power, it increases your swing arc. Very happy with it! Service is untouchable!

I use the one club to help me with my release and also the help strengthen my back I am glad I have it

I have used it only twice and have already seen a difference !!!! I am sold !!!

Everything about it!
Teaches you speed , power, sequencing & build strength .

Great tool. Immediately showed me how to improve my impact,compression, lag, timing and shallowing!!!!!! And i only used it 3 times for 5 minutes each time!! Will only get far better from here!!!

Picked up 5 mph with my irons in the first week.

This is the best training aid I bought. It fixed my back swing and down swing timing.

A fantastic speed training device. I will work with the ONE all winter. My goal is to increase my club head speed 5 mph faster.

I'm not one for gadgets but this device is rather neat. It's one thing for somebody to tell you what you need to do in order to get to X mph and how to produce lag. It's another thing to develop the feel with direct feedback. Feeling the ground force, rotation and tempo needed to make it all work is very eye opening. I set the resistance to the 120-130mph setting and it took some serious work - while I'll never game a speed like that, I think it's great to train the noggin that it's possible.

I am loving my ONE trainer! Having a sense of release and impact while building speed is what sets this product apart. With traditional over speed training, I would start moving faster for sure, but I would feel like an absolute maniac and would never have the sense of making an actual golf swing that would produce a functional shot. With the ONE, I can do any of the exercises and feel the load and release of a real good swing, and immediately pick up a club and hit it better and farther right away.

Great product. I bought it for release timing and with just 4-5 sessions I can feel my timing better which has led to much more flush impact. And even with the light resistance I can feel the strength training. Next for me is starting to up the resistance over time.

Different than any other swing training device that I have used. Provides a unique feel and the combined benefits of training both power and speed. I am still early in my application of this device to my training but the early feedback has me expecting great results.

I absolutely love this concept of a swing trainer. You can train for speed and also learn how to release the club as well. Looking forward to using this everyday to help my golf game.

So far so good is compact size is great for carrying to the course for warm up. As well for being able to swing indoors with limited space.
