| Stainless Steel Sprouting Kit, 4 Pack | Rust Proof 316 Stainless, Curved Mesh, Fits Most Wide Mouth Mason Jars | Grow Your Own Organic Sprouts from Seeds, Sprouter

I’m new to sprouting. I bought these lids and a sample seeding package. The lids are very easy to use. They fit Kerr quart jars I bought a long time ago, ball pint/quart jars I bought within the last 5 years, and ball half gallon jars I bought last week. I had most of the seeds successfully sprouted. For the ones I failed, I think it’s the problem with the seeds, and not the device. It’s very important to drain as much water as possible. I sometimes shake the jars, put the jars in the upright position and then upside down and repeat a few times, to get water out.The lids are very strong and sturdy. Based on engineering, material that are twice as thick will provide four times strength (2^2) and eight times stiffness (2^3). So it’s not linear. The concave design is a plus. Not only it adds out-of-plane stiffness for the structure, it also adds slightly more area for air circulation. It makes draining easier too. I just wish both pieces were made of 316 stainless steel. I hope the seller can give us “old” customers a discount and can sell the new 316 stainless steel mesh separately when it is available.Also, please do not equate “Made in China” to inferior quality. Price probably has more correlation than country of origin for things that are not extremely high tech. After all, the tolerance of one of the rails built by Chinese was so amazing that an American presenter at a conference stressed that again and again. He said before he actually saw it, he didn’t know it was possible. Anyway, I’m willing to pay more for a product that can last longer and produce better results.
