How about the quality of the magnets?

To ensure the quality of the products, every production procedure is inspected strictly by the professional QC team from all aspects. Besides, the Trade Assurance order will protect your payment, and make sure that we deliver on time and manufacture quality products as required.

Will the magnetism be weaker after years of use?

Yes, magnets do weaken over time. If you store permanent magnets correctly, neodymium magnets will likely lose less than 1% of their flux density over 100 years. The magnetism decline is neglected, that's why we call it a Permanent Magnet.
