TRY BEFORE YOU BUY: If you want to evaluate or test equipment before purchasing, we recommend to set up for an equipment rental first. Returns will not be granted for issues other than verified Manufacturer Defects. Please contact us prior to paying for a rental order, and request a rent-to-purchase authorization. We will set you up with a standard rental, and if you choose to buy equipment within 30 days of the original rental date, we will contribute 60% of the rental price (not including shipping) towards your purchase. Rent-to-purchase authorizations cannot be granted after rental orders are placed.
