What Problem We Solve
Where Wellness Ranges Actually Lose Money
Buyers lose money on wellness ranges through fragmented suppliers, untested models bought on photographs, generic devices they cannot differentiate, and motor failures that surface as warranty returns. One factory covering 11 categories, two-unit trial orders, OEM branding and a one-year warranty each remove one of those.
Fragmented sourcing
Eleven categories from one factory means one deposit, one artwork loop, one consignment and one salesperson who knows your account.
Buying on photographs
2 units per model as a trial sample order. You handle the device before volume money moves.
Nothing to differentiate
Logo printing, customized packaging, and new product development on request, plus ODM development when a catalog model is not different enough.
Returns after launch
One-year product warranty; problems are handled directly by the sales contact. Brushless motor and aluminium alloy options exist specifically to cut failure rates.
