Also check out Project Farm's channel. It's a little more automotive based, but the product comparison tests are extensive. If you ever wondered which type of drywall screw could resist the most sheer force or if you can use Zippo lighter fuel in an engine, this is a great channel.

My only criticism is sample size is usually small (3-5 samples), and no checking on variation between product lots. But, it's one guy doing all this for free, so I can't complain.
