I have had mine Yong Heng for now for almost 2 years. Still running well and i would say I have around 12 hrs on it. I only use it to top off my Guppy tank so run time is limited which is usually 10 mins at a time.I usually run to 2900 psi then then fill up to 4500 psi.
Frequent oil changes and keeping it cool is key.
