Amazon can be a minefield buying certain products.
There are 90,000 lumen flashlights with 20 hour run times, surge boards without surge protection, chargers that don't meet Australian standards, high powered retina burning laser cat toys, USB-C hubs without HDCP or mislabeled ports.
Reviews on many of these products can't be trusted as users don't fully exercise these products. With a torch users turn it on, think "Woah, that's bright compared to my AA powered torch", leave a 5 star review.
Should Amazon be doing more to verify claims made by sellers?
As a reference, Torque Test Channel did some testing on flashlights. They also have another video on laser pointers.
Should car websites verify cars? Should pharmacies test all drugs they stock?
Consumer law protections allow you to return goods to the seller, so this helps reduce the risk.
Market places aren't in the business of measuring product efficacy. They are in the logistics business. If one supplier is letting them down, they will be dropped due to commercial reasons.
