Having previously worked in the medical device industry I have seen the testing they do on products that have already been tested and approved and I can say it is very intensive. To see that products from other companies are being produced without significant testing is very disappointing. It is not surprising entirely because the FDA can go years without checking up on a company, but usually consumer reports of a failed product usually will spark an FDA investigation. The FDA when alerted is extensive and thorough in their investigations and normally will have zero hesitation in shutting down or ring fencing a company. The company will then either face heavy legal issues and/or a multitude of fines and other sanctions. I do believe low testing is a large issue, but I hope that the fear of the FDA and the aftermath of a failed audit keeps companies away from sloppy development.
