I bought one 2 years ago and have had good luck with it on tall plants bearing small to medium tomatoes (haven't tried beefsteak size yet). I did need to supplement it with 2-3 slender stakes for a couple of errant branches, but it was more atractive than the mass of stakes and twine I've used with traditional cages. I neglected to bring the cage in over 2 cold winters and even so it didn't crack or break and is still usable this year. I bought 3 more last month. Seems to me some people reviewed these cages before actually trying them and without understanding how they work. I think this is a marketing problem. They shouldn't be presented as a tomato "support" because this seems to confuse people who expect it to stand up on its own or come with a stake. (I very much prefer supplying my own stake.) Rather these cages serve to train the plant as it grows upward without tying. And they do so attractively with a fairly small footprint. They are easy to store (if you're not too lazy to bring them in over the winter.) The part that is hard to grasp is that the plant and cage combine to give it the stability you want, but it is essential to use a sturdy stake which is tall enough for your plant and pounded well into the ground (2 ft. or more). I find the "flimsy" lightweight plastic to be a plus as it's less likely to break the plant if it tips over (or when I happen to drop it while setting up!) Since the plastic spiral is able to give a little, I think the plant conforms to it more naturally. As for the screw fastener cracking, I use a metal stake covered in notched plastic. The screw catches on a notch instead of having to dig into wood so I don't have to screw as tightly. My husband tends to wear down or break plastic fasteners because he over-tightens and I wonder if that is why some people had trouble with cracking. So far I haven't had any thing break. I do think the pointed tab securing the cage to the ground could be a bit longer so it grabs better in fluffy soil. I miss the choice of green over black, but if it makes it less expensive to produce and keeps the cost down, then sure, black is fine with me! I'm being rather detailed as I admire innovative ideas and feel this invention deserves reviews from people who have actually used the product. I gave it 4 stars because I feel the cost of shipping and handling equals or exceeds the cost of the cage itself and I don't see a reason for that. I also don't know how it would work with super-heavy fruit. But I very much like the cage and think it's worth developing further. I'd like to see it distributed in stores where it might be displayed in actual use. I think it would convince a lot of people.
