OEM Smart Tag & GPS Tracker Manufacturer

After three years of working together with this Factory, we have learned "details matter" with regard to quality. We started with an order of 500pcs anti lost devices, with every batch being subjected to a 72 hour simulation by their QC team. They test performance at the extremes of hot and cold, BT signal penetration through walls, and drop resistance. Last year during peak season, when we needed an additional 30,000 units immediately, the factory managed to re-order the production lines and pulled everything together to deliver within 72 hours, with a defect rate of below 0.3%.

Because we are cross-border sellers interested in both European and American markets, we expect the best product compliance and user experience. Annie Factory's customization capabilities are beyond what we had expected, as well as security for CE, FCC, and RoHS certifications. One of our customized model products sold the Black Friday before last for over 10,000 units monthly, and the reorder was returned to us in 15 days.—a supply chain speed rarely seen in the industry.

Due to our quick product turnover, we had to meet a pressing deadline for our spring collection: getting pet anti-lost devices from prototype to mass production in 20 days. The project team at this factory showed remarkable efficiency: they finished mold development in seven days, delivered 12,000 units 15 days later—three days ahead of schedule—and produced 3D samples with personalized cartoon designs and IPX5 waterproofing in 48 hours. In order to guarantee prompt delivery to our American warehouse, they even covered the emergency air freight expenses. Our trust was strengthened by this collaboration, and we now have a "7-day prototyping + 10-day delivery" express lane, which gives us a two-week advantage over rivals in terms of market responsiveness.
