Hate to reply because if you get a dud it looks bad. BUT... the Chinese water cooled spindles, and a Huanyang VFD are the staple for most builds here, and many a machine you'll find on the market. They're covered in Chinglish marketing speak (sometimes the claim of 4 German bearings is a little optimistic... sometimes not), but they generally work well. Nice a quiet, and usually low run-out on them. Cock all power below 6krpm, but above that they perform well.

I can't help but think, however, for the same cash (or less) you'll find a 2.2kW one - you claim you don't need the power, or the larger ER20 collet. Until you do.

They're a good buy. Provided they work :)
