When we receive equipment, we thoroughly function test it. If a machine is fully functional we resell it as “Used” on clearance and pass savings on to our customers.
Used equipment is ideal for residential or personal use, where the machines will not be exposed to the regular usage they are originally built for. Used equipment may have some minor cosmetic flaws or noise, but will not affect the performance of the machine. We do no recommend purchasing “used” equipment for commercial usage.
Used machines have a 30 days warranty.
“Refurbished” equipment is restored to new-like mechanical and cosmetic condition.
Equipment is dismantled, sanded and repainted, internal components are thoroughly inspected and any worn or damaged parts are replaced. Consumables such as decks, belts and batteries are always replaced. The machine is cleaned, reassembled and tested.
We recommend refurbished equipment for facilities, institutions and gyms where customers expect consistent usage throughout the day. Refurbished machines have a 6 month warranty.
