Is it safe to use arduino boards?

I'll happily relieve you of the stress of worrying about possible damage to those - just ship 'em to me - I promise I'll look after them 

No kidd. Tried to blackmail the devs for one also lol. Those Zbook will easily run a 500+ parts assembly without over heating and capable of fast 360/3dof real-time motion on those large assemblies. Nearly zero noise on the comm (4800Mbps error-free) too. All good fluid motions stuff. One of those "you get what you pay for" thing... buy with confidence!

I've quit using them at the shop, when I get back home and on my PC it feels like a lada with a flat tire...
