Have you Tried the Topsy Turvy Tomatoes

I haven't tried it myself, but one of my best friends decided to try it this year. Every time I go over to visit, I have to go out back and check out his plants. Two of them are doing very well and have lots of tomatoes on them, only one fully ripe so far. But we still have a lot of summer left. The third plant, did not do so well. He ended up taking it down, because it broke off. At a certain stage, these plants try to turn up to the sky. And that was the problem. When this particular plant started curling upward, it broke the stem right in half. I myself ended up planting some tomatoe plants really late this year. They've only been in the ground for about a month. So far, just a couple of blooms. Hopefully I will end up getting some tomatoes off of them, because I love fresh tomatoes!

I have looked at this product with much interest but never tried it. I can't understand how the plant and dirt stay in it upside down. I also wondr if you can use the system for other plants? I have a largen garden plot so I do not need the topsyturvey. I am just very curious. The low yield makes me feel glad I never invested in one.
