I too have been using
Original Grip Buddies for the past 5 years or so, on several of my motorcycles. But they are not perfect. Their surface starts wearing out and splitting after about a year of use. They also tend to slip and rotate after a while on the grip on some bar surfaces, like the ones on my Royal Enfield, especially when exposed to hot temperatures. Plus, at around $25 a pair they are not all that cheap.
I have now switched to both
Grab-on foam grips and the similar
Grip Puppies, covers that do not wrap but slide over the ends of your handlebar ends. They, and similar products, can be bought for around $13 a pair on both Amazon and many motorcycle shops, like the BMW shop that I frequent.
Now what gets really confusing is the name of the products. I have
Grab-on and
Grip Puppies on my shelf, still in their original packages and they both are the same type of product that are just foam covers that slide over the bar ends. However the wrap-around grip covers, as are shown in Bmadd34's video, are sold under the brand name
Original Grip Buddies, now just called
Grip Buddies, as shown at this link:
