The Nub Techs

[Sickgirl]

Has anyone used them? I’ve heard very mixed reviews

I know a load of people who have… generally the consensus is that if the “accuracy” is 70% or above, they’re pretty confident. If they mark it lower than that, I’d treat it as a guess.

There are a load of free places that’ll do it; Nub Techs and the like have just made a career out of it, and therefore do a lot and are pretty accurate as a result.

But it does all depend on your scan photos. Some are really clear and obvious, some have no nub at all and there’s no way to guess, some are in the middle and you can make an educated guess…

I’ve only done it for a bit of fun.They asked for other photos as they could only partially see the nub and then said 85% girl…
I’m not so sure….

You can see the nub quite clearly here.

I'd have leant girl too; but I'm not sure it's the clearest nub... There seems to be some imaged cord, which makes things harder!

But I'm no expert at nubs, and have no affiliation at all to the Nub Techs or any other nub company, I just found it interesting when I was pregnant.
