Hannah was great to deal with. She was very professional and polite and had good product knowledge about keyboards and accessories. Thanks to her diligence and professionalism, the order was processed and dispatched promptly, and I was confident throughout the purchase process. I ordered a sample of various Outemu switches, keycaps, and accessories and was very satisfied with the quality. I'll certainly be ordering more from Shenzhen Manthon Technology. Excellent service and quality, thank you!
