I do not have experience with this cage. I got a SS cage from a well known cage company and it started to rust within weeks. The cage was made overseas. I don't know how to verify if a cage does have at least 304 grade SS. That would be my worry. (It has been months but they say a new cage from a new batch is on the way).
There are several cool features about that cage, the large door, the shelf, the cool feeder doors-but I would think if your bird sits on the door, it's going in the bowl--may not really matter as they kinda go everywhere anyway.
I would recommend the cage company I used, but only after they get me a real 304 cage--at this point, I do think they think the factory ripped them off too. Expandable habitats is a SS cage here that gets consistently good reviews.
I googled the company under both names and couldn't find anything except on ebay. They have been a member since 2013 yet they do not have enough feedback to generate a feedback score. That seems odd. It would seem if there were making cages since 1974, that they would have a larger presence on the internet. I am curious how you found the site/cage.
