30 yd gain in 10 weeks. Very pleased. Will keep putting in the work.
I have been using the stack for just over two months, the hardware and the app are great so let’s skip to results. after the foundation program my good drives averaged 20 yards further than my previous good drives, 230 vs 210 yds in normal conditions (not young or flexible and 140 lbs). The app recommended “full speed spectrum” for the 2nd program and after 3 sessions my driver speed is up another 3 mph and 9 more yards in addition to the foundation program, that’s about 30 yards in 10 weeks! Make sure to hit drivers AND irons/wedges at the range or simulator after every stack session to let your brain/body adjust and keep making good contact. NOTE: For some reason it took 6 weeks for my driver air swing to catch up to the stack “driver eSpeed“, driver max air swing was 7 mph slower than eSpeed at first but I guess I subconsciously figured something out, and they are the same now. Also, the speed gain isn’t in a straight line, I was slower in sessions 8-10 than session 2. It also took about 6 weeks to regularly see personal bests on the golf course. Don’t get discouraged if this happens to you, keep pushing.

Works good if you stick to it
I was a bit skeptical about it at first, but I just finished the foundation program and swing speed increased 15mph. I had slight regression due to not doing it for a week and half but once I was back on track, I saw gains weekly. Going to explore different programs now but to me it is worth the money if you want to increase speed and distance.

Stack System works!
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.

Worth the investment!!
I believe this thing is the real deal. I felt something after the baseline secession and a one mph increase after the second. It’s a little pricey, but I think it’ll be worth it after 30 days. I would definitely purchase again.

Helps with swing speed
Over the course of 2 months it helped me increase my swing speed by 5 mph. The grip is sufficient. It comes with weights that are interchangeable. It was worth the price. It’s durable and functional.

Unless you know how to swing faster - don’t bother
Does not teach you how to swing faster just logs your speed - kinda pointless. Spoke to Stack customer support and they were helpful and suggested I stick with it for longer. They say it is all about training your muscle memory. Well I took a two week holiday and my speeds reverted to when I first started - so my muscles have very short term memory! I’ll persevere and see how I dod
