I love the Stack System and it really works. I train every 3 days as prescribed by the app and I’ve added 20% more speed on my driver swings. This is real results, no BS. The Stack launch monitor was seriously delayed in shipping. I got really frustrated and finally reached out on the Stack IG page to complain. They got it sorted out with Amazon and my Stack launch monitor arrived 2 days later! So it seems like Amazon was the real issue, not the folks at Stack. Great customer service from Stack, not so great from Amazon. BTW - I’m no longer an Amazon Prime member, at least in part due to them not being helpful with this order.

The stack system is amazing, have been very impressed with this overall. The club and weights are super easy to use and given my speed training is done indoors with limited overhead space, much better for me and my set up. The club has a very nice grip on it that is plenty tacky (can be changed too). The end cap goes on and off easily (do need to be careful to not cross thread though, I recommend turning the club not the cap). The weights are great and outside of losing one, they will last forever. Nothing unique with the shaft, just graphite but that is fine, is a hybrid length. The real magic is in the app and guided programs. If looking at this, of course you are most interested in speed training, and the guidance from the app is awesome. I have speed trained with another device and the stack blows that device out of the water as it adjusts based on your metrics. I had decent speed starting with the stack but in the offseason I have gained an additional 11 mph club head speed after two programs (was stuck with old device for a bit). Its hard to get board or tired of the training because it tracks your personal bests for swings and sets, so the built in competition with yourself is very motivating. Also has a grit score that tracks your commitment, and for some reason keeping that number high is motivating to me (they know how the human mind works). The app has a ton of learning material as well. Also amazing with the app is the putting and wedging now active. The wedging is great because forces you to learn your carry numbers better and gamifies the practice with benchmarking against pro so can see how compare. Really seems like I've practiced so much smarter this offseason than previous years. Some things to consider: - It is not cheap, you do get your first two years of the app included so that is nice initially. IMO, the annual fee is worthwhile after the first two years. Way better investment than other useless training aids) - To get the most out of this, the Stack Radar is needed for wedging, but its a really nice radar that goes in bag and onto the range very easily. Can use other radars though so can always get their radar later if already have one that works. - Not yet on android as of time of writing (I switched to iphone to get going). Overall, this is probably the best investment in my game outside of lessons and would highly recommend despite the cost. You will no doubt get faster, get more clear on wedge distance, and improve your putting. Just do it already if considering.

A great way to get some training practice in without having to go down to the range. A fitted weighted stick and guides along with the application will help you in no time. Gave this to a friend on the college golf team and he really liked it and said it was very helpful for him and his teammates. Good value for the money. Helps to train you for accuracy and your grip.

I am a high handicapper. My driver goes 230. 3 wood 220. 7 iron 150. Etc. There is hope. I did not add the sonar speed reader to my regimen. I purely swing this thing in the living room and work on my form in slow motion, slowly building up the speed of the swing based on the whistle that the tip creates at varying velocity. I am not using their app. It is too disciplined for me. I like this a lot and work through different weights for tempo. I have been using this for two weeks now and have gone to the range twice since using this. There is a noticeable difference in my ball hitting. Many more flush hits. More slight draws than fades. All are encouraging me to put in the work. Which is what a good training program is all about. This is the right tool for sure! Alongside tempo and form, I am building muscle in the right places and building stamina as well. Two weeks in, in a month maybe I won't feel so beat by the13th? Yes this is expensive. Even more so with the sonar. So you need to be serious about improving your game.

To be honest I was initially intimidated with the weights and the app and everything else. And yes it did take me a while to figure everything out. But it was easier than I expected. The app is included for the first year and is available at a reasonable cost after that. You must have an Apple phone to use it. The app is required to be able to use it effectively. I'm a fairly regular player but by no means am I a scratch golfer. With the cost and the time you put into it this is for fairly serious players only. You get advice and training help from some of the best minds in the golfing world. And from what I know and have seen personally it will increase your hitting n a remarkable way. And to boot the process and training from the app is really fun! I'm beefing up a little from the weights. I highly recommend this for those who really want to improve their golf game!!!

I play over 200 rounds of golf a year. Like all golfers I am always looking to improve. I saw this and grabbed it. First off it is very will made. The grips on many swing aids are not good. This one is great very tacky. The set itself is all well machined and fits together great. The weights are all nicely machined. The QR code would not work for me but I am thinking it is because it was to the Apple app store. I didn't notice when I ordered this that the app is not available for Android devices. Very disappointing there. I went to the web site and the app leads you through the training of using TheStack system. I have a launch monitor that Bluetooths data to my phone but I don't have an iOS device. Will have to figure this out to take full advantage. In the meantime I have found videos on how to use this to increase your swing speed and will get to work on that.
