Fit and finish is average for a Chinese product. Some panels are not perfectly flat or straight. Assembly instructions are vague and incomplete. That said, assembling the cage was straight forward. All materials are indeed stainless steel (non-magnetic). All welds are solid and clean. The above mentioned cosmetic flaws in the framing/panels are not overly apparent once assembled. ****the only big issue with this cage are the seed catcher panels. They are bolt together and fit poorly (very loose). The corners are sharp and dangerous, especially for young children. They are not easily removed once installed. They appear to be a poorly designed afterthought, so I have decided to leave them off until I can modify them to work properly. Since I work with metal, I am fussy with my evaluations in this profession. Therefore my ratings may a bit harsh. The main cage deserves a 3.5 star rating, while the seed catcher panels dsserve a -1 star rating.
