Great price for an electric sprayer and I might get it just for that. The herbicide, however, is pretty weak. It's a contact herbicide, which means it'll kill any cells it touches and only those cells. That's why you need to coat every leaf to kill the entire weed. And why you need to use it when weeds are small. The biggest advantage is that it works fast, often within minutes. HOWEVER, it will not kill the roots, which are underground. So if you have weeds that can regrow from the root, e.g. perennials, this won't be very effective. The instructions even say that you may need repeated applications, and even then it won't work for large-root perennials like pokeweed and Chinese yam.

In contrast, a systemic herbicide like glyphosate gets absorbed into the leaves. It then gets transported throughout the plant, including the roots, permanently killing it. A big advantage is that you don't need to coat the entire weed. You can just spray a single leaf and it'll still kill the whole plant. That means it'll work on large weeds. In fact, I've eradicated large morning glory and wild grape vines by spraying just one leaf. And you only need one application. The biggest disadvantage is that it may take up to a week before you see results.

Do you have a recommendation for what you are suggesting of a common weed killer that goes on sale regularly?

Alternatively you can buy 41% glyphosate concentrate online. This is much better if you are going to use it more than spot treating. Buy a $10 pump sprayer and mix it yourself. Takes two minutes and will save you lots of money. It's hard to find in stores now because of the Bayer Roundup issues. Don't worry, you aren't going to die using it a few times the people that were getting cancer were using it regularly for their jobs. I just got compare-and-save brand off Amazon a week ago. You can also adjust the potency depending on what you are trying to kill.
