Indeed, they
look to be...

because these folks will copy even the cheapest Yamaha. Quality Control is most of what you pay the extra $$ for.
Edit: @MovinTarget: Everything you said may be true from the perspective of a seasoned player/modder, but keep in mind they make their profits from beginners or people who would like to try the bass for the first time. Show me a serious teacher who will recommend the Glarry over a Yamaha or Ibanez.
I would argue that giving a newbie an absolutely perfect instrument from the beginning could hinder development, but I come from the old-school "adversity build character" mentality where I sometimes have a practice bass with high action so that playing for real is a breeze... If they are new I think the most important thing is that its playable, but not perfect and Glarry can fill that bill just as well as a starter Squier CV, Yammy TRB or Ibby SGR. The big counterpoint is that Glarry has *very* beefy necks and yet many find it more comfortable b/c their hand cramps on a thin Ibby.
When YMMV, its nice you didn't pay too much for the bass. If you bought from Glarry direct, you'd be surprised how amenable their customer service is!
As for Teachers; that's assuming the serious teacher even knows about Glarry...
Glarry came on the scene less than 10 years ago.
A serious teacher is going to recommend what he knows, if he doesn't know Glarry he's not going to recommend it. If he doesn't know Guild, he's not going to recommend it. If he doesn't know Epiphone he won't recommend that either. If the serious teacher is in his late 60s and grew up on the Beatles, he might only recommend Hofner. Why? Because if they value their position as a teacher they want to talk about what they are knowledgeable about.
But this doesn't really have anything to do with teacher opinion/experience. My brother bought a bass without even telling me he was taking it up, turned out it was a "Burning Fire" style Glarry or something off Amazon. He brought it over, and I was able to drop the action waaaay lower but the intonation ended up be almost perfect as is and I filed maybe 5 fret ends total...
I would argue that is a comparable experience to the purchase of a entry-level Squier, Yamaha, and maaaaaybe an Ibanez but I'll admit they are usually pretty good out of the box.
Don't forget that there are plenty of QC controversies for established brands too... Anyone remember the Gretsch Junior Jet with it's <cough> humbuckers???
If nothing else, I was able to show him how to care for his bass and give him pointers for tweaking performance. For $70.
Seriously, why are we hating? So many of these bases share parts and just have a different name stamped on the headstock.
