i Have been using my clover flex since April 2019 and the device is excellent. It takes payments in lighting speed and for my deliveries i am able to email the customers receipts and capture their data for my mailing list. I have just recently had to do my pci compliance and Julie helped me to complete the form so it took me about 20 minutes rather than the hours i spent on it before.Excellent machine and excellent service. I will never go back to a normal terminal again.
