SPECIFICATIONS
Manufacturer
Rocket Espresso makes hand-built espresso machines with classic Italian design.

Warranty & Returns
Standard warranty covers the replacement of defective parts for up to 12 months from the purchase date.
30-Day returns – returns are accepted if initiated by the buyer within 30 days of receipt. Returned equipment must be in the same condition as received, per our inspection; otherwise, deductions may be incurred. A 20% restocking fee applies to espresso machines, brew equipment, and grinders. This fee covers physical and mechanical inspection, additional setup/testing, and restocking upon receipt. The buyer is responsible for return shipping to our facility in Austin, Texas, along with any associated costs.
Water Quality Requirements
Water quality testing for your espresso machine is crucial for achieving optimal flavor and ensuring the longevity of your equipment. Good water enhances the taste of your coffee, while impurities can cause scale buildup and damage to the machine. Damage caused by inadequately treated water will void the manufacturer’s warranty on the machine. Chloride requirements only apply to machines with steel boilers.
