Finally a sturdy and flexible mirror. Great quality and should last a lot longer than ones I've used before.
Putting Mirror (Steel Edition)
Keeps my shoulders and eyes aligned and shows me what the putter face should look like when it is square to the target. Definitely the most useful putting aid I've ever had and is used regularly. Bought as a replacement for the acrylic version which had served me well until someone accidentally stood on it and broke it. That won't happen with the steel edition.
i think using glasses is much heavier and also making a scratch
A must have. Until you don't use it you can't figure out that you're NOT in the correct setup. A little heavy...but hopefully more durable than plastic ones
