||I have this product now for 2 weeks and have skated a few times. The first time the ride wasn't as smooth, but now the work fine and give a smooth en fast ride.
I just noticed that the cover plates leave a very small opening so you can see a bit of the interior. My old ones had a ring of some sort, to hold the plates in place, they are missing with these ones. Not sure if due to the very small gap, filth from the road will easily seep into the interior and stop the balls from rotating smoothly. I'll just have to see...
