It’s amazing how many useful golf training aids are out there. It’s even more amazing how many crappy devices, trying to act as a "golf training aids", are out there.

You’ll have to decide which category the Mentor Putting Mirror belongs in, as I’ve been unable to find any reviews or more detailed info about it anywhere on the net. The descriptions the merchants give are pretty vague and they all state the same thing - "a small, simple and portable mirror that can be used indoors or outdoors to improve your set-up, alignment and path, which are the three crucial elements of putting."

Anyway… I can guarantee the Mentor mirror is good for at least one thing. Since it’s small mirror, you can store it in your golf bag/cart and use it anytime you need it. Possible uses include, but are not limited to, blinding your opponent on one of his major shots. Remember to appear sympathetic and curse the "damn sun" afterwards.
