Guide lines come straight off this mirror after 15 mins use.
Hi after receiving the mirror to use with the Mat and cup I found the guide markings on the mirror coming off after 15 mins use. Not happy as I have cheaper mirror I've used for a while and nothing has come off this. All you get is a replacement mirror card to change over which after using that one has started to do the same.
Very good quality product showed up one problem in my swing immediately, ie eye position not over the ball . Then swing path of my club when using the guides with the mirror. Drive for show putt for doe so they say 🤔
