The company that made the original(?) aluminum plate went out of business six(?) years ago after being in business for only three or four years (how many plates can you possibly sell?). But
another new business popped up about a year ago and is selling a somewhat similar product for a similar price.
Many "hit and run" companies only sell their product(s) for a short time. It's like being a "one-hit-wonder" band where you have just one popular song for a short time.
This seems to be a trend in business these days: someone has an idea for a product, they crowd-fund it (or they give up), manufacture the product, get a web site, sell a bunch, and then close up shop when the demand stops. Relatively minimal investment and minimal risk involved.
