Have had these for two months and use them often. For the price they are excellent. Light, so they're forgiving if you hit yourself. Although I did accidentally give myself a black eye. Solid for beginners. I've dropped them a bunch and they're still solid and going strong. Bearings are great quality.
Pros:Durable, light weight, cheap, great bearings
Cons:chain links not welded, but that's not really necessary
