MAZEL Golf Club Groove Sharpener Tool for Golf Iron,Wedge - Aluminum Alloy Shaft Golf Club Cleaner with 3 Replaceable Heads,Fit for U & V-Grooves Re-Grooving Tool

Great golf tool.

It worked well as it should. But I clipped it to the outside of my bag and it came unscrewed and unfortunately lost it.

The golf groove sharpener works great on my wedges and irons. It hooks right unto your golf bag and has a retractable cord. If any dirt gets into the grooves it is easy for me to quick clean it out. It has 3 different heads- pointy head, straight head and oblique head. All are useful. When you aren't using the two heads, they fit inside the tube. It is so nice to have them all together and they won't get lost.

I was not expecting any miracles on my most worn club, but I did feel a slight improvement when using the fingernail test. I probably won't use the cleaning tip as I find using a brush to be far more efficient and effective. The included carabiner also makes it easy to attach to a golf bag. Overall it'll probably improve/maintain the grooves on your clubs if they're not terribly worn down, but don't expect any vast improvement if the clubs' grooves are too far gone.

The media could not be loaded.  This groove tool is well designed, well built and functional on and off the course. I like how it stores the bits inside of the tool itself. It also comes with a retractable leash and a clip for easy access. I also like how this is a stand alone tool in that it doesn't come in a set with 3 or four other accessories that you possibly already have and don't need.It does a good job of refinishing grooves without being too aggressive. The removable tips all worked well, but there are only 3 of them. They lack a couple of other sharpening implements on that are other styles of golf club face regroovers. That is the only con I could come up with as it did a decent job on my club (see video). I did need to spend a couple more minutes off camera, but it did not take much time to regroove one club.

It doesn’t work well at all, save your money

I don’t know if this product even works. Came unscrewed immediately after putting on my bag between the car and driving range. Found it and reattached only for it to unscrew itself on the front 9 at some point and disappear before getting any use out of it.

This handy little cleaning tool clips onto your bag so it can be conveniently carried right where you need it. The clip seems to be sturdy and the retractable cord works well. As you can see by one of my pics, I definitely need to have a club cleaner handy as I am not the best at keeping up with that! The cleaning tool works well and gets the clubs nice and clean. The sharpeners also work nicely. I'm never going to be a pro, so I'm not sure how much that will improve my game, but every little bit counts! The tips are conveniently kept in the tube so you can have everything right there in a nice small package that doesn't get in the way, but is there when you need it. If you're like me, I would recommend not opening the end and taking out different tips unless you're somewhere on a nice clear surface, because dropping one of the tips in grass could easily mean losing it. I'm quite happy with it.
