This is like a patio version of that gardening system I learned about from you, can't remember the name, but the concept was sort of a raised "chimney" structure for a compost bin, placed in the center of a garden bed.
I did click on a couple of earlier articles and noted that the original target price was $200... and the current price in their online store is a "sale" at $359. I guess the plastic extruding equipment was more of an investment than anticipated.
I was curious, so I did a quick calculation... Even at that price, if you spend $5+ / week on salad greens and fresh herbs that you could grow in it, it would pay for itself in a few years, in addition to the fun and healthy-food factors of growing your own. Without factoring in potting mix, seeds, etc., figure $5/week, for 20 weeks per year, May - September... that's $100 savings per year toward the price of the system. So in 4 years, the structure is paid off, and it should last twice that long.
The design is elegant in its simplicity. I won't invest in one myself, but I'm glad to know it exists!
