Ah Ha! Now I remember, just didn't remember the thing's name. It's one of those things that are on my 'to-do' list, just haven't gotten that far yet.
Some thoughts and conjectures.
It's a small antenna. Want to say less obtrusive than a full length dipole, but that's debatable . Should be able to be almost over looked cuz it's sort of close to a TV antenna (nuther' debatable thingy). Say it's for HDTV!

It isn't an 'equal' substitute for a 'real-live' antenna, but it's certainly workable as a back-up as claimed by the advertising (I like the fact that 'they' aren't claiming it's the next 'miracle-do-everything-bestest' antenna around). And it can certainly fill an antenna requirement for 'back-up' or those hard to fit places, especially if you don't have the required 'spaces' to start with.

I have no reason to doubt the claims made for this thingy so far. So far, they haven't been that extraordinary, disregarding what the thing looks like. Used with the proper feed line and tuner, the 40 meter version ought'a be usable on bands higher than 40 meters. In that regard, it 'matches' the claims for the G5RV. And also like the G5RV, it don't 'do' miracles.

Like any rotateable 'dipole', it's directional to some extent. Getting it higher than the typical 15-25 foot altitude can't do anything but help that characteristic. I do like the fact that it would only require a 1/4 turn to cover all directions!

Easy to put together? There, I have my doubts, at least for me anyway. I've tried the 'spiral' thingy with other things and it does require paying attention to what you are doing! (Ended up too many times with a gob of spagetti when I've turned loose too soon.) Doesn't sound like it's too difficult though, sort of.

Enough of that. It's still on my 'to-do' list! I wanna see what it'll do. Scale it to size and it ought'a look great for 2 meters on my aluminum foil helmet, don't'cha think??

I was on the air with the guy who makes these on 80m the other night. It's no miracle antenna, but it does radiate. It's a great antenna for people who have no room to work with.

I've seen them up close at the local hamfests, it's solid enough but again, it's not a NASA design. It's plastic tubing for supports and is basically a dipole, center fed with the ends in a spiral. There may be more thought into the dimensions etc for electrical properties, but that's basically what it is.

The guy was running it on a rotor and there was a slight bit of difference within 90 deg turns so it does have some lobes to its pattern.

From the night I talked to the guy, it was maybe 1 S-unit as he rotated from peak to dip. Heh, no way it has that level of gain, and I'm close to where he was for sure and he was say an S7 where all the other locals on 100W rigs were S9+10 or better. He was just above the noise level.

maybe there was suppose to be a decimal.
"1.0 to 1.4 dB signal increase in transmit with 90 degree rotation"
that would be more like it. it looks like something comparable to a isotron, which is just as good as a dipole (compared to nothing) just more compact.
