We have been working with Jia Xi Lun for three years and have purchased its electric soap dispensers for use in 50 of its hotel chains. The product is sensitive (response time 0.2 seconds), the IPX5 waterproof design is perfectly adapted to the bathroom environment, and the battery life is up to 8 months (80 times a day on average). It is particularly worth mentioning that its silent motor is 15 decibels lower than that of competing products, which has won praise from many guests. The after-sales service responds quickly. Last year, there was a packaging problem with a batch order. Jia Xi Lun reissued new goods within 24 hours and covered all shipping costs. This responsible attitude allowed us to increase the purchase volume by 40%. At present, this product has become a standard configuration of our hotel, with an annual purchase volume of over 20,000 units.
