Have you ever worked on a NIBU machine?

We currently have a Nuova Simonelli Premier Model 1 at our cafe. It ran well before we moved a few years ago, and unfortunately it didn't do well on the journey. The heat exchange has blown on one of the heads, we have been chasing down leaks, and the other head can't hold a consistent temp when pulling shots. We've had it serviced regularly, but it just keeps throwing us problems. Long story short, we are on the hunt for a good used dual group on a budget (can't afford a new $15k one atm)

In searching for a good used machine (which is next to impossible to find in Atlantic Canada especially where we live), we ran across this machine, the NIBU NB- KS535, on Amazon. Amazon lists the brand as generic, but it is actually from a company called NIBU, they have a few other coffee related products like grinders and smaller machines. But we can't find any information about it, no reviews online, and we've have never seen one in the wild. Has anyone used or seen one of these before? The price is attractive, especially for a new machine. However we know something this cheap is likely not going to last, and too good to be true, but we are curious. Appreciate any info you have! And if you are on the East coast and have a machine to sell hit me up! https://www.amazon.ca/Commercial-Group-Espresso-Machine-3-Phase/dp/B0FP4J1ZY5/
