Total 2 yrs plus.
First owner is Roi$%#, I am the 2nd owner.
For those who know the 1st owner and me personally, you will know that the chiller have been well taken care of.
I have previously invited Derrick to check up this chiller as I know some bros have to top-up gas periodically.
After checking, Derrick gave me a thumb-up. According to him, a chiller will not need to top-up gas frequently unless it have some minor leak/s.
