I was a little leary of ordering these tire irons/bead breaker because of the price and the lack of reviews or videos but went ahead and tried them. I pulled off the rear wheel of my 1150GS and I have to say they work just fine. After a few trys to loosen things up with a little lube, if you get the first tool all the way in to the rim before inserting the second tool the bead pops right off. They are well made, very light and pack easily. Love the fact that I don't have to carry a seperate tool to break beads along with tire irons.
Terrible product. Worked for over an hour to break the head on the rear tire of my Triumph Rocket 3 Touring (180/70 R16) Metzler 880 Marathon with no success. Followed the instructions to the letter. I do not recommend this product.
