This is a set of aluminum screw handy! The quality is good, however my taste the price is a bit high, in fact even if manufacturing is satisfactory, there are imperfections in hammering streaks that can not slide by turning some imperfections, although covered by a basic anodizing quality (it's not on the polished anodizing the end of treatment) can interfere a little because there are little balls that have formed. The products have certainly the stay too little time in the acid baths or polishing drum / cleaning after machining. In short, when my order was the product available in Prenium delivery that had the most value price. Quality is in my opinion well below what the actual price of manufacture is! The keyless version is probably more beneficial, especially since the tightening can be done without! Delivery: RAS Packing: RAS
