When i received the box they were shipped in the plastic packaging for the wheels was split open. I had a tremendously difficult time getting my bearings into the wheels. I was extremely frustrated, and I initially wrote a very negative review. Then I came across the note on the packaging that says to use lubrication on the bearings and a bearing press to get them in. Initially I tried using a c-clamp and even a hammer to get a few in! (Hammer was obviously a bad idea, but I only slightly damaged one bearing.).. Anyway, I found the trick is to put a little WD40 on the outside of the bearing and inner hubs of the wheels and then you can push on different sides of the bearing until it goes all the way in. Some bearings were too difficult to go into one wheel so I used it in a different wheel without issue. Thankfully I was able to get them in and tried them out tonight! They were much grippier than my older wheels but I'm starting to get used to them!

Went from nylon hubs, to these.Gotta say, they make me feel more “connected†to the ground, grip well when they need to. transitions make me feel more solid, and they roll pretty fast. I find myself rolling faster than I intend to, which is good for me >:-)

These are ok. Wish they were available in bigger sizes like maybe a 62x34mm. I sold a set of skates that had them on the plates so I only used them a couple times. I prefer my Anabolix wheels.

Everything arrived after it had been shipped across the country Twice!The delivery box was ripped open. Almost like somebody had been going through it. To the point the postmaster wanted to sign it as damaged.The product overall looked as described. I am not disappointed with the product. More or less the delivery and the care of it.
