I purchased Atlas Bradbury knobs in Warm Brass as well as Oskar pulls, from Wayfair. The knobs are heavyweight and great quality, as were the pulls. There were some minor issues with the paint finish of the pulls (otherwise this would be a 5 star rating); however, this is an Altas hardwares quality issue not a Wayfair issue. Wayfair sent a replacement pull when I addressed the issue with customer service. 

The knobs and pulls were well priced and actually on par with ones which I had purchased (also Altas brand hardware) from a bathroom and hardware specialty store, for my kitchen renovation. 
The warm brass matches well with the Delta Champagne bronze of my plumbing fixtures.
