My Bincoo immersion dripper lost its steel ball during washing

Reviewed: Bincoo glass immersion dripper (source SKU unspecified)Regional reference: BINCOO V02 immersion coffee dripper (United States and European Union)

I lost the valve ball while cleaning my Bincoo immersion dripper and bought five 14 mm spares. My receipt records the size; I didn’t report a sealing test.

A screenshot of a buyer review above a coffee-dripper product listing. The reviewer complains that a replacement steel ball costs 16 yuan and says five 304 stainless-steel balls bought elsewhere were smoother and better quality. The listing shows a transparent dripper and carafe set with 600 ml capacity and 50 V-shaped filter papers.
A printed order receipt shows a 14 mm specification, quantity 5, unit price 0.2860, and total ¥1.43. A cartoon onion wearing sunglasses and holding bubble tea covers part of the receipt.

The steel ball is easy to accidentally lose while I’m washing the dripper. I asked the shop’s customer service about its size, but they didn’t know; they could, however, send me one at a high price.

Leaving this here in case someone finds it while searching: my immersion dripper is from Bincoo, and I bought 304 stainless-steel balls with a 14 mm diameter. Buying them myself cost less than two yuan for five.

Making money this aggressively from an information gap really isn’t necessary.

A purchase record without a sealing test

The receipt records five balls marked 14 mm, and the owner reports buying them as 304 stainless steel. The post does not document a post-replacement sealing test. It provides a part-purchase lead for this unit, rather than a verified repair or a fit standard for other drippers.
