Its correct several main brands are manufacturing in China but hopefully with a proper quality control.
The pure cheap Chinese non branded equipment??? nobody knows if there is any QC/QA performed any where in the production and feedstock line.
A small back-up light, no problem, a DSMB, no problem, a reel and line for before mentioned DSMB, have a few of them and its reaching the APEKS/Mares standard of alu reels with flat line.
But a BCD, drysuit, or regulator, cylinder, straight out of China/ebay/Ali...... no never.
