Anyone bought parts from RobotDigg? Are they decent quality?
Seemingly good stuff. I still think their shipping costs are jacked up, but other than that…
I have ordered from them a few times, as Ray said, shipping is a little high, so I make sure I place a large order all at once, then the shipping is reasonable, if orderering small quantities the shipping is too high. But the quality of the parts is very good, I have never had an issue with the parts I have ordered.
Also I have had good experience with them. Shipping is high considering most of china stuff ships for way less. In my experience though, when they ship it as far more reliable time frame. I have bought stuff from other china places that took more then 40days to arrive. Their stuff usually is here in about 10days. The quality of parts are very good in my opinion.
idem for me, a reliable source and quality stuff imho, well packaged as far as I remember (bought multiple times but it was like 1-2 years ago). I would again.
@Adam_Steinmark I’ve ordered multiple packages from them and gotten fantastic reuskts every time. They are friendly and helpful where they can and once I needed some m3 grub screws after I placed the order and they just threw them in the box for me when they weren’t even listed on the site. They can supply most everything you need. 
I would suggest ordering big, and fast, pay for air shipping and buy with a friend, it costs alot, but hey, your shipping from China!
Good luck with the build!
