I believed that Zanflare was one of Gearbest’s house brand and was unknown who actually manufactures them, but I was mistaken, they actually have a website where they list contact information for Shenzhen Haiweili E-Commerce Co., Ltd.

They were very cheap at 11.11, now they are out of stock. With Gearbest you never know when they will be in stock again.

Edit: edited answer with new information.
