Reviving this thread because the season is back on and its time to start practicing seriously again. As someone with disposable income and only one hobby that costs a lot of money, I have spent some of it on golf training aids and I will give you guys a review to help you decide if you really want to spend the money or not.
This thing is pretty decent. Both this and the next thing I will put up really help me swing on plane with my backswing but this allows me to swing faster. I have a tendency to take my club too far inside on the take away and end up just all over the place so this helped me way more than other tools. Would recommend
You can't really swing with this super fast but it will help you with slower swings to get the take away and back swing into a perfect spot. If you aren't on the range, use this. If you are on the range, use the black ball. Would recommend
Don't waste your money on this. You can set up tees to make sure your putting stroke is straighter outside or golf balls indoors and you will get better training than this. Heck, a chunk of wood also works (as long as its straight). Would not recommend
Careful with this thing. It does help with the timing of the swing but its a very small stick and you can lose the back swing very quickly making this useless. If your backswing is perfect, then its a good tool but wait until then. Most likely would not recommend
Not a bad option. If you are having trouble with holding your backswing in place then this helps but you can always put a credit card in your glove to get the same effect. Probably would recommend
These are wastes. If you are having trouble with this, just put a towel under your armpit like Vijay Singh use to do and your problem will go away. Would not recommend
Dumb tools. If you want strength and power with the swings, theres forearm drills to do at the gym and other equipment I will show below that do the job better. Would not recommend
These are the speed sticks and if you search speed stick golf, you will find some variation. They are club length training tools with 3 separate weights. One is lighter than your clubs, one is the same weight, and one is heavier. You can find different workouts or just swing them whenever to build up strength and speed. Can attest my 7 iron went from my 140 club to my 175 club by using mostly these. Would recommend
Initially wasn't a fan of this one since it didn't help me with my speed and power but once I started using it as a way to stabilize myself in every position while building strength there, it became a little better. Would probably recommend
