Is the "gone viral" Tomato tying tool worth it? Let's find out

Update: A few weeks and many uses later, it's a persnickety tool. Sometimes it just doesn't want to work and I have no idea how to fix it. Then, I go back to it later and it's just fine. So maybe it just messes up if it's used too many times in a row, I don't know.
I hope I'm not the only person who falls victim to the product ads on Facebook or Instagram. This is one of those products. I do usually spend A LOT of time tying up tomatoes during the growing season. I was seriously seduced by how easy this tool appeared to be on the ad.
Let's see how it worked out for me :)
