Monoprice is a good place to buy a lot of things, first and foremost ethernet and A/V cables. Some of their other products are good, but it’s a bit of a crapshoot as to which ones are good and which ones aren’t. As always, do a little research beforehand. The New York Times runs a review site, Wirecutter, that is honestly pretty good - they come to a lot of the same conclusions I come to independently, but they’re always going to make lib consumerist recommendations, so take that into account. They won’t recommend used items, or alternatives to major retailers like Amazon, or super privacy- and security-focused stuff, or really add any kind of ethical consideration into things. No ethical consumption, I know, but you can be slightly conscious about where your money goes.
