Stay away from Clover if you are in the market for a POS system. If you are already a customer do not upgrade to the duo. The old 2018 version is far better than the new system. The old system had a built-in battery that helped during power outages. The new system does not. I had never experienced freezes with the old one. Now, they are common. I have to restart the system many times when I open in the mornings since the customer facing display will not turn on. Unfortunately it’s too late for me to move on to a new system. You on the other hand, have options.
