A few months ago, I purchased a North Group 102mm triplet apo directly from the manufacturer. While optically excellent, the telescope's focuser originally had a part missing, which the company subsequently supplied for me.
Unfortunately the focuser was still defective after installing the missing part, so I emailed Gilman Zhang, the representative. He organised for their courier company to pick up the focuser from my home and send it back to China for repair or replacement.
I received a brand new focuser as replacement today.
I had purchased a Moonlite, so did not really need the replacement, but you cannot knock North Groups service!
