Simple but very effective
This guide will most certainly help you with your putter stroke. You would need to develope a series of drills to create the muscle memory.
Good product and great service
I ordered the putter guide with the rail and it wasn’t in the package that came in the mail. I emailed and asked where it was and without any questions they apologized and sent another one which was on my door less than 2 days later. Works great for what I need! Amazing customer service
