Do yourself a favor and buy this tool, will save almost an hour when servicing your bearings.Works once you get the hang of it, poor directionsBefore I say anything, let me say: I don't really know anything about this stuff. So maybe you will want to disregard this middling review once you've read it. Or maybe you just want to skip to the next review by someone who doesn't admit up-front they don't really know anything.That said... It kind of does the job, removes bearings from skate wheels. But I could only get it to work on wheels without a spacer ring between the bearings. Before this product arrived, I used a bolt to pry the bearings out of the wheels I bought, and when I replaced them, I didn't put the spacer back in a couple of them because I was curious to see what difference that would make. So when this tool arrived and I tried it out, I found it worked brilliantly for the wheels without spacers and it seemed to do nothing with the wheels with spacers. When the wheel has a spacer in there, I just couldn't seem to get the balls in this puller to grab onto anything. I'm too inexperienced with this stuff to know if that's normal, or if I just don't know how to properly use this. It's possible that this tool will do that job and I'm just too new to know how.Is it normal for this tool to only work with bearings without a spacer ring in there? If so, then I guess my 3-star review is unfair because I was judging it by an unfair standard.Again: I don't know anything about--or have experience with--skate wheels. I only recently bought some wheels and bearings as part of a project to build a camera dolly. Maybe you'd rather listen to people who are skaters or roller derby people.Ok for an emergency pull on a single wheel. Doesn't seat bearings squarely. The Cal 7 is by far a superior tool. Cal 7 Skateboard Bearing Press Tool https://www.amazon.com/dp/B079ZNH4R7/ref=cm_sw_r_apan_i_CS83DKZBTZN8HB1TMYS6?_encoding=UTF8&psc=1I live by the beach in Miami and use my longboard to get around almost everywhere, including to and from work as far as 6 miles each way. with all the puddles, sand and surprise florida downpours, i end up cleaning both mine and my girlfriends bearings quite often. I personally don't like using my trucks axles to pry out the bearings so I wanted something that I could use regularly to do this without damaging the bearings. This tool is amazing, its the size of a large keychain trinket, just a few inches long but made sturdy of all metal. The two balls on the end retract when you push the button at the top, allowing you to push it through the bearing, release the button and easily pull the bearing out, if you have spacers like me, you can use this tool just like your truck axels, insert it into the bearing, and use it as a lever to pry the bearing out. it fits so well into the center of the bearing that this causes no damage whatsoever. and it works just as well to push them back in.I bought this tool out of sheer laziness, but also ti spare the bearings that I felt were still usable. Instead of forcing them out with a screwdriver, it was better for them to be removed by this too. I bet there is another tool in my toolbox that I could have used other than a screwdriver to pry the bearings out, but I wasn't in the mood to find it. I resorted to buying this tool, so that it would be easier. It does work great though. If you are a casual skater and want to change your own wheels and bearings, you should think about it. It really does a great job of getting those bearings out of those old wheels!Puller works as expected, but the handle is a little small and not ergonomically contoured well. The edges of the handle bite into my fingers if I have a jammed bearing in a wheel. The hole for a key ring was a little smaller than needed for flexible positioning in a pocket, and far enough from the edge to make installing a ring harder than it needed to be. Over time, the hole will wear wider and the ring will tilt more.Overall, this is a solid tool that works as intended to pull bearings from skates, but if using steel inside spacers, the bearing has to be rocked out slightly before the balls of the tool will grab it.Works great ??
