    5 star review  Square provided very high levels of quality at a very reasonable price. The equipment was installed with near military precision and before we knew it, we had a state of the art system up and running. They took all the stress away and provided us with excellent levels of service. Our business is protected which gives us peace of mind. In our industry security is of extreme importance. I am glad we chose square to work with. They are the best choice by far!
