They are very responsive and always willing to solve any problems I have with them. The customer support at roundtower is fantastic! All members of their team were great people to work with. They understand what we need their companies products for when it comes to our needs. Their pricing was fair so there wasn't too much room for error if you wanted a product or service from them. We haven't really felt like they had anything they've failed us on either, other than maybe getting an email out within 24-48 hours sometimes isn't possible due to holiday schedules and times. If your looking into purchasing equipment, be sure to ask all questions about the specific brand/model, as well as how long they will last before needing some maintenance done. It's important to know everything down to minor things pertaining to this type of piece of machinery.
