Absolutely love this grip. Found an old belly putter that I wanted to turn into an arm-lock putter. Found this grip during a google search and glad that I got it.
Awesome grip. Perfect for armlock putter.
I like how the armbar grip takes the wrist out of the putt, thank you
Hard to imagine that a grip this size would be so comfortable and allow me to control the putter. Enjoying my re-learning of how to become a better putter with Jumbo Max!
This grip does everything it says it does!
The JumboFlat 17 is much larger than any other arm lock grip out there but much easier to lock in against your forearm. I have been using an arm lock method all winter but struggled somewhat with a traditional sized putter grip and locking it in. No more struggles and it feels very comfortable. I feel that I have complete control over the putter now with the larger grip to hold onto. I was even able to get this .580 diameter grip over the .620 diameter shaft on my Acculock Ace!
I recently converted to the armlock style putting grip. I found this grip to be perfect for the armlock putting style.
An oversized grip for the "armlock market". Had tried SS many times, but to no avail. My only concern is immediate wear on the edges from in and out of the bag. Will be watching that.
Great product - the flat side against your arm is the difference maker.
Not really a flaw as a personal wish for this grip. Works great for arm-lock putting, it is over sized for a comfortable loose grip and the large flat surface allows for great awareness of the putter face. My only wish, and this is a personal opinion and might not work out in practice as well as I think it would in my head, is that the flat surface was more rounded at the bottom only the grip where my hand would be holding it. Maybe not round but maybe more like the top half of an octagon. That way it would still have the flat surface for locking against the arm and the hand would have a flat surface to keep awareness of the putter face but also the give a slightly more ergonomic area for the lead hand to grip the putter. Also a couple of notes to ponder for anybody thinking about switching to arm-lock style putting but haven't researched it fully just yet. Using an arm-lock grip will give your putter face a super extreme forward press and for most putters result in a negative loft at contact so you'll need one of two thing to happen. 1. If you're comfortable moving the ball way forward in your stance and can still strike the ball square then you're fine (unless you really want to putt with a negative loft). 2. If number 1 isn't something you can do then you'll need a putter with about 9° loft. As for me I just move the ball forward and so far love the arm-lock style and would recommend giving it a shot. Happy putting!
