^ Started out as ASOTV, but you can find it in Walmart and drug stores now. Great tool.
^ Never used one myself but I have a friend who has. It works! Pretty well too. If I were doing tomatoes again this year, I'd prefer it over the monstrous tree-like messes I had before.
^ I don't use these either but I have another friend who fosters dogs and she has one. They're pretty sturdy. And the cover comes off for washing and it's easy to put back on. If I had a small or elderly dog, I'd pick one up.
