katrinacoco 7 Colors LED Light Outdoor Inline Skate Wheels 64MM/68MM72MM/76MM/80MM/90A Flash Roller-4packs/Lot (70MM)

I just got these for my son. I know some have had issues with them, but there is some knowledge needed to make these work. For starters, you need to have bearings for this to work. My sons skates had wheels that already had bearing built into the wheels, when we got these, I had to go to a sporting store to pick up bearings. Once I put them on the wheels worked, but the bearings center was too flush and the wheels had to be loose for them to spin, which stopped the lights, so I added washers between the wheels and the frame it screws onto, and now they work extremely well. He broke them in outside and they worked exactly as the pictures posted. very bright in the dark.

I really like how these are available in wheel sizes suitable for children’s inline skates! I also like that the wheels feel much softer than the durometer rating advertised. They actually look and feel more like an indoor hockey wheel than an outdoor recreational wheel, which is to say they are much lighter and softer than my Seba Luminous LED wheels and thereby perfect for a tiny skater. But this is as far as I can romanticize these wheels as they did not light up consistently for me, and when they did light up they looked nothing what is pictured. The quality of manufacturing on the included bushing and hub is so poor they couldn’t function properly—squeaking when they work, scraping up against each other when they do not. And when lights did activate, they showed up like tiny hot spots (think xmas tree lights) instead of diffused (as pictured). I returned them but I did want to highlight what I liked because I am hoping this will encourage improvements on the design.

The central bushing is too small and the wheel wobbles. I am returning these.

They dont fit nor work just received them today and I'm already processing my return I give up

Good.
