As a baseball fanatics fan, I bought this and hope to share something on the common questions that people want to know about this product. Bought this product couple days ago, the performance vise, hard to tell yet, my son still trying it out. This is an inexpensive piece of equipment but could have big impact on people's baseball swing. I own this and also the Grip-N-Rip bat grip taper (GNR grip): https://www.amazon.com/gp/product/B015KCSRM0/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 I will compare this product against GNR grip because people often confused them as the same thing, they are similar but not the same thing. Briefly, this product is like a cover go around the knob, so it provides cushion especially for your power-V part of your swing, material is very soft. GNR grip goes on the bat handle, usually sit tightly against the knob, it kindly changed a standard straight handle to a flare handle and with finger grooves, material is much, much stronger, also provides a little similar cushion to prevent knob press again your palm during power-V. 1. install ability People asking this probably because they have experience with GNR grip, I have owned GNR grip for several months now, have put it on and took off from a few bats. So from experience it is very hard to put on and take off. We are talking about good 5 to 10 minutes of hard work if you have really strong fingers; otherwise, could be like mission impossible to do. Very hard to put on, but once it is on, it is very secure and material is super tough. On the other hand, this one "power pad bat knob" can be put on really easy, 10 or 100 times easier than GNR grip, it is too easy so that it does not feel very secure after installation. 2. Adaptability I have a few bats from youth 28'' to adult 33'' different brands including wood bats and their knobs vary slightly from one to another, this product fits them all, pretty much the same way as long as you install it with the small hole goes on the bat FIRST. I think anyone find this not compatible probably install it wrong way. 3. Can you use it as a choke up ring? Probably not. First it goes on the knob and stays there, so you can not stack multiple pieces up like you could with choke up rings; second, it is too soft, won't provides a hard stop behind your hand. By the way, even though I said this can't work as a choke up ring, but actually that is what I am using this for. I feel my boy's bat is tiny bit heavy for him, I wish he would choke a finger up or so, but not as much as a inch like many choke up ring do. With the thickness of this product as a knob cover, it seems fit my purpose so far, it will provides 1/4'' to 1/2'' or so clearance from the knob. Overall, I personally like the design, but not sure about its performance yet, too soon to tell. I do wish the material is much stronger, maybe like GNR grip if manufacturer is listening, it will work much better in my opinion. I am not surprised to read some batters went thru several of these in a season or they can fall off during swing for a strong hitter, it is because the material is too soft and it is too easy to install (therefore easy to come off too).
