Lately I've been seeing ads for long handled (3 to 4 ft tall) weed pullers. So I have plenty of weeds and would like to not continue bending over or sitting on the ground and am curious about these long handled things. I recently was at a wedding (not mine, thank you) and met a woman who used one (brand unknown) and thought it was junk. Of course I promoted Cobrahead, the best tool ever. Anyway, per usual, I digress.
Here's a few examples.

Anyone use one or have opinions?

Those do not look like they'd be much use in my garden.

You probably should define specific plants that you are warring against, and particular media and garden types that you expect to use above tool maintaining.

when I have large poke plants that have become too numerous, a shovel after a recent rain works very well.

When I have large evening primrose plants? A shovel, or if soil is moist enough, just hand pull.

Blackberry briars?
Either a shovel, or just fireplace gloves... either way, I usually will see that plant again in a month or two.

Smilax?
A shovel...

I can't visualize a plant that above "tool" would be utilized against.

As far as turf maintenance?
What little is on the place is growing between the wheel tracks on my drive way... a string trimmer is enough to maintain.

I have the Grampa's Weeder, your 2nd link, and it actually works quite well and is built very well, it's very sturdy. My neighbor also has one and likes it. It can sometimes leave a piece of root that might break off on those real long roots, but that happens when you're down on your hands and knees and doing it by hand too, so it's really not an issue for me and my bad knees.
