ATC 2.5KW spindle review - possibly the best Chinese CNC spindle out there!

full review of Chinese ATC spindle, unboxing, first impressions, finish quality, vibration test, noise test, installation and results.
I was looking for a reliable manufacturer of cnc spindles and it looks like i found one.
I can honestly say that this is possibly the best Chinese spindle on the market, with really good support behind.
also they provide very high quality tool holders from company in Taiwan: Parfaite http://www.parfaite.com.tw

Spindle tool holder which i got is a ISO25 taper and ER20 collet.

Spindle price was 1450usd.
