when issues arose, customer help was from an off shore help line, with someone reading from a flow chart and often could not provide the answers needed, Several devices failed along the way, and when they did even tho it was leased equipment, our company had to buy new ones on our own dime, and when we decided to not renew the contract they insisted on getting working units back or “they would charge us”. Overall they they are not very helpful, and not a great system for a small grocery store. Also helpful hint, if you need to ship all the equipment back, it might just be cheaper to buy it and throw it away rather than ship it back.
