Most bad HIFU purchases are visible before payment, in the questions a seller cannot answer. This is the vetting sequence to run before you transfer money.
Which seller types should you compare?
Manufacturer, authorised distributor, marketplace listing and reseller.
Each has different support after the sale. A marketplace listing may be the cheapest option and also the one with no service route, so match the seller type to how much support you need.
What documents should you request?
Specification sheet, certification for the model, warranty terms and invoice.
Ask for shot counts per cartridge in writing, the certificate covering the exact model, and the warranty and service terms in the quotation. Our authenticity page lists the same documents we request from suppliers.
How do you verify a serial number?
Match the serial on the device, the box and the invoice.
A traceable serial is the difference between a genuine unit and a rebadged one. Photograph all three before switching the device on, and send the number to the seller for confirmation if anything does not match.
Which payment methods protect you?
Methods with dispute rights and a documented invoice.
A written invoice naming the model, serial range and warranty is what you rely on later. Methods without a chargeback route leave you negotiating directly with the seller if the item does not match.
What should you check in the first week?
Box condition, seal, model match, accessories and function.
Report damage or a mismatch immediately, with photographs and your order number, and keep the packaging until the device has completed a full session successfully.
FAQ
Where can I buy a HIFU machine safely?
Anywhere you can verify the specification, the serial number and the service route, whether that is a specialist supplier or a marketplace. The test is not the channel but whether the seller answers technical questions in writing and supports the machine after delivery.
How do I spot a counterfeit HIFU machine?
Warning signs include no serial number, no shot count for cartridges, packaging that does not match the model ordered, and a price far below comparable listings. Verify the serial with the seller and keep the invoice, because a traceable unit is what allows a warranty claim later.
What should I check when my machine arrives?
Inspect the outer box before opening, confirm the seal and the model match your invoice, find and photograph the serial number, and check every listed accessory is present. Run a full test session before discarding packaging, and report any fault within the first days.
Conclusion
Vet sellers on documents rather than on price: shot counts, certification for the exact model, warranty terms and a traceable serial. Photograph the unboxing and keep the packaging until the machine has completed a session. See returns and refunds for what happens if the item does not match.
