Alturn 645lmg poor build quality
 

I picked up 2 of the servos and had the same fault with both. A side mount snapped off the first whilst simply screwing it to a servo mount (I tried gluing but that was a waste) so that was that one done and on the second servo both sides snapped whilst running in my 2wd buggy. I'm not an overly aggressive driver and know I didn't hit something big when it let go. There's very little material that actually holds these parts to the main case- about a third of the little lugs width is all that is attached.
Anyway, this is just to steer people away from these servos. Buy nice or buy twice, my lesson is learnt!
I've tried uploading pics but having problems

That's interesting, I've had or have a few alturns but never the low profile. Never had a problem with mine. I do use Savox low profiles and again never an issue with them either.
