Don't forget said pre-release devices are often different, sometimes substantially, from the released version.

LTT and many other reviewers don't even go into depth and often get details critically wrong, such as falling victim to Nvidia's GTX 970 "4gb memory" scam, because they didn't know how to test VRAM and discover 0.5gb of that memory was severely degraded in performance.

They also don't appear to have any process to vet people they take money from, given they're partners with Gigabyte who dumped PSUs onto the market they knew were dangerous, and several exploded as a result.

They aren't reviewers because they have a conflict of interest. If they fairly review products, companies will not send them review units.
