Review on 🏌️ Slot It Golf Swing Trainer: Patented Driver Design! Achieve Perfect Swing Path with Black and Red Poles. Training Aid for Better Irons and Woods Swing. by Johnny Nguyen

This is a good idea and it seems people have had success with it, the problem with using irons is that they haven't game improvements are really suitable for modern irons. I have Callaway cheaters and if you get the red stripes in the right position the head of the stick is really too big to even swing back without hitting them. You can spread them out wider which helps some but the other problem is that when you pass and hit the red bars fly out, I understand they can't be solid there but something where they just fold over and over again going up would be better. So plan on walking back and forth a lot to get them and if you are some distance away it might not be the safest way. Right idea, just not the best for beginners using irons to improve their game. This means it might not be for everyone as I doubt a low handicap would use this.
