The putting mirror and gates are excellent quality and the storage bags make it convenient to keep them with you in your bag. You can use the mirror with or without a ball to make sure you are aligned properly and practice your putting stroke.Great product!Frankly, there was nothing I haven't liked about this device. It comes with four putting gates--of various widths so that you aren't frustrated when you first start grooving your stroke. Second, it allows ways of measuring your backswing and through swing. Furthermore, it has a grid which insures you have your shoulders properly aligned. Other putting mirrors have some of these features--but few have all of them. And on top of that, the packaging is first rate; this assures that your mirror will not get scratched up when not in use. I would give this six stars if given the opportunity. Use it--and you will definitely see improvement in your putting stroke!This is my first time using a mirror. I’m paying more attention to shoulder, alignment, and eye placement and the ball is rolling to my target. Very user-friendly, with self-explanatory lines printed on the mirror. I decided to try the mirror in lieu of another putting lesson. Good decision. Looking forward sharing this tool with my golf buddies/lady golfers.This alignment mirror is well-made with a good reflective mirror, wide enough for me to see both my eye position over the ball and my shoulder alignment simultaneously. It has properly placed holes so you can secure its position on a green with tees for outdoor alignment training. There is a "T" mark and a ball groove that facilitates retraining your brain against perceptual bias, or at least helps you become more aware of your aim biases. There is also a carry bag that can polish the mirror and prevent scratches. Finally, there are holes on both sides of the backswing path that you can put tees in, allowing you to practice reproducible backswing lengths.I'm very pleased with this purchase.I purchased the putting mat, I didn't buy the putting gates, so this review is only for the mat. This is an awesome product, the packaging is the best I have ever seen. The mat comes in a hard cardboard box that is a work of art, truly beautiful and functional. And if that isn't enough, you also get a velour carry pouch to take to the course or range and not worry about scratching the mirror surface. There are numerous alignment lines to help with your practice. If you're after a putting practice mat, this is the product for you. Perfect for home or the practice green.I thought I had an issue with my mirror and wrote to the company to explain the situation. The owner responded to my email within an hour. It turns out the issue was my mistake but he could not have been more curteous and accommodating to rectify my problem. For that reason alone I felt compelled to take a moment to give a 5-star rating to this company. And the mirror is pretty awesome, too! The carry-case is such a great idea - the mirror will definitely be going into my bag. I would not hesitate to order again from Back 2 Basics!!
