The first unit I received was extremely poorly constructed. The sink basin was not level with the frame and a large amount of silicon caulk was used to fill significant gaps. The frame itself had large gaps where the frame elements are screwed together. The welded joints were tight and well crafted and it would be terrific if the while piece were welded. There were also some small imperfections in the basin itself.  Wayfair was great and sent a replacement immediately. The second unit was better in terms of the  attachment of the basin and was free of blemishes, but there are still what I feel are significant gaps in the joints. Overall it's not bad for the price, but a little quality control and improvement in fit and finish would make this a five-star review.
