[LG G Flex 2] br0adband:
I ordered one of these cables a month ago from the eBay link in post #9 by Tiker above, it just arrived a few minutes ago and I have to say I'm a bit disappointed. The photos above (perhaps the one the OP got was a bit different from mine) show that the microUSB portion of the cable sits flush with the bottom of the Flex 2, or at least the photos shown make it seem that way. Of course the one in the OP was from a name brand (PLESON) and not a totally generic piece of crap like the one I got from the eBay seller so please note this entire post is a rant about the cheap one - the PLESON one is apparently "what this should have been" so, my comments below are about the cheap one from the eBay seller. ;)

The one I got is too long in terms of how far it juts out from the Flex 2 as pictured (if you click these thumbnails you'll get the full size images so, be aware):

The cable itself seems to be of decent construction but that's about all I can say at this point. The microUSB aspect needs to be roughly one-half as long as it currently is to get it flush against the bottom of my Flex 2 - and yes it is most definitely pushed into the microUSB socket as far as it will physically go so no I'm not just lightly pushing it into place and complaining about it. It's obvious the one I got is a cheap one, you can tell much by looking at how badly the microUSB housing on the plug is: it's all dented and bent with a lot of non-smooth surface issues in the one picture above.

There's a possibility that each of these could be completely different; the OP's model appears to be pretty close to flush as already noted, but in my situation that's just not the case. I measured the length of the microUSB plug itself and it's 9/32" which is quite long indeed. It seems like the length should be ~3/16" which would make it damned near perfectly flush when inserted fully on any microUSB port out there.

This of course makes this cable and the magnetic aspect of the microUSB plug completely useless to me unfortunately. Another thing: the microUSB plug is so loose in my microUSB port that when I gently tug on the cable - hoping to cause it to separate as designed because it's held in place by that magnetic force - guess what happens? The whole thing comes unplugged from the phone but the microUSB plug stays attached to the cable because the magnet is just a bit too strong. :(

Oh well, it's not like I paid $30 for this or something, just about $4 shipped so, it's not worth going through the hassles of returning it to China for a refund. I'll keep it, might find some use for it at some point, who knows.

Another problem: the pogo pins in the cable end aren't fully "loose" on the one I got - in fact, one of the pins was half-stuck in position and not fully extended. I had to take a pair of forceps and pull it out to get it working properly again; my needle nose pliers were too thick to get a grip on it but the forceps worked fine - I highly recommend getting a decent pair of forceps if you're into working with small electronics components.

I fixed that issue and it does work but again the issue with the plug sticking out too far is the main one. It's such an amazingly simple idea but I suppose it's in the execution to get it right but then again I did choose to save some cash and I did buy from the eBay seller so, I'll take the blame on this in the long run.

Do I recommend this for anyone else? I would have to say no because you might end up getting one like mine where it just sticks out from the bottom of the Flex 2 way too much - on mine it's literally 1/8" out from the phone. The press images in the eBay ad show it completely flush against a device it's used with and that's just not the case. microUSB ports are standardized so they should all be exactly the same depth from port end to deepest insertion point and this plug on the cable is just about 1/8" too long honestly but it's following the standard I suppose. Wish I could just cut it to length but that would end up destroying it entirely so that's not a workable solution.

Great idea, crappy execution would be my opinion. Had high hopes for this to save wear and tear on my microUSB port(s) as I'd probably use it on my next device when I replace this Flex 2 but, as it is I can't make use of it in general so it'll just go in a drawer till some reason to pull it out happens.

Buyer beware, that's my advice. The OP seems to be really happy with his/her cable(s) so that's nice, but I'm definitely not with mine. The pictures in the eBay ad technically aren't even the product I bought - the pictures show one (they're renders more than likely) with a 3/16" microUSB plug length which is of course spot on where it should be and not what I ended up getting.

Good luck...

ps

Note that the one I got from an eBay seller is not the same item that the OP got from Amazon and after looking at a review video of the one from Amazon (the PLESON brand one) it does apppear that those are using microUSB plugs that are definitely a bit shorter, not by much but enough to get the plug to sit as flush as it can against the device when inserted. It's quite possible (and likely) that the cheap POS I got from the eBay seller is one that just doesn't have any quality control and uses microUSB plugs that are, as stated, just too damned long.

My issues are with this cheapy version, spending more money on the obviously higher quality one from the Amazon seller (at 3-4x the cost) will probably be much more useful to anyone interested.
