Resurrecting an old thread here because I finally realized the problem with these wrenches is not me.
I saw these a few years ago on Amazon, thought they were a great idea, and couldn't buy them fast enough. I only use them a few times a year, and they never seem to work. It's hard to use them to find the size of the nut, I can never tell which way they go on, and they don't seem to engage the nut very well.
But the biggest issue, and one that I didn't realize until I read this thread, is that they need 1/6 of a turn to ratchet. That seems obvious to me now, but I guess I always thought they ratcheted like, well, a ratchet.
I was doing a radiator on a friend's Ranger last weekend, and tried to use one of these wrenches to remove the transmission cooler line nuts. I couldn't find the right size, couldn't get it on the nut properly, couldn't get it to engage, and the flex head made all of the above worse. When I finally grabbed a regular flare nut wrench it broke the nuts free right away, and I just spun them off by hand.
I realized the wrenches had never worked for me, did a search on GJ, and now I see that it isn't me. These wrenches will either go to the back of the drawer, or if I get super-motivated I'll put them on eBay.
However, I apparently haven't learned my lesson yet. I saw these on Amazon a while ago and bookmarked them. Does anybody have any experience with them?
