AliExpress Skate Bearings REVIEW

Ordered cheap bearings from China titled "SEBA TWINCAM ILQ-11 Minature Ball Radial Ball Bearings Good Quality Skating Bearings ABEC-11". The BS description aside, are they any good? The price was just €12/$13 with free shipping for a full set of 16 bearings.

I compared them with the cheapest bearings from the local discount store (NILS EXTREME ABEC-5) and high quality Rollerblade SG-9 bearings.
