Adjustable-Stroke Massage Gun Warranty and After-Sales: Terms Buyers Should Negotiate
Percussion guns fail in three predictable places, and all three are cheap to design out and expensive to service. What to agree before the first container.
Massage guns fail in ways that are predictable enough to plan for. Three components account for most returns, and each can be addressed at the design stage or in the contract rather than case by case.
The battery pack is the first. It is the most expensive single part and the one most affected by how customers charge it. Agree a guaranteed capacity threshold across the warranty period and a policy for replacing packs separately from the gun.
The amplitude mechanism is the second. Repeated use wears the linkage, and a device that develops play loses stroke precision long before it stops working. Design tolerance and lubrication specification decide how long that takes.
The accessory heads are the third, and they are not really a warranty matter at all. Foam heads compress, silicone heads tear. Publish the expected life of each and sell them as accessories; a customer who can replace a head does not open a warranty claim.
Aolemon quotes twelve-month warranty on massage guns, guarantees a battery capacity threshold, supplies replacement heads and battery packs as orderable spares, and provides a failure analysis report on any returned batch so that a design issue becomes visible in the first order.
