Frequently Asked Questions

Please read our FAQ before sending us a message.

Payment may be made by check or credit card. We accept Visa, Mastercard, and Discover. For payments by check, order processing will begin one business day after the check is received. For payments made by credit card, order processing will begin one business day after the order is placed online.



We ship direct to customers in the United States only. For international sales, please find and contact a local distributor. All orders are inspected and required to pass quality control prior to shipping. The length of delivery time varies per product and is indicated on the product's information page. We use FedEx for all shipments and send a confirmation e-mail with the tracking number once your order has shipped. You can check the current status of your order any time by logging into your account and going to the View Order page.


We offer free walk-in demos and training on equipment at ten major trade shows in cities across the country every year. Click here for a list of meetings at which we exhibit. We are still in the process of establishing branch offices, so we are not yet able to offer free on-site demos outside of the Boston area. In the meantime, you can also opt to rent equipment on a month-to-month trial basis without a long-term commitment.


All purchased (not rented) products returned within 30 days are eligible for a full refund of the equipment value, minus shipping and any travel costs incurred during installation. We do not charge a restocking fee as long as equipment is returned in its original condition and original packaging. A refund check will be issued after inspection is completed, generally within 30 days after equipment is received at our warehouse.
