At the risk of sounding like a glorified Amazon reviewer…
Checking my Amazon order history, I can see purchases for wall socket chargers (mains to 2x USB), a 3-port PCI-E to USB 3 card, and a mains powered SATA to USB 3 adaptor. All used frequently, never had a problem with them. The wall charger is the best one I own: fast charging, reliable, gets the job done. As a computer tech person, their stuff works for me.

I got some usb cables some time ago. fancy models. both got broken wires in less than a year. their lifetime warranty was taking forever until I updated my 4 star review to a one. got and email instantly saying they shipped new ones to me and if I could change my review to 5 stars. this was via amazon, they even used the same Shipping address as the purchase. never heard from the warranty email.
they did send new ones of an upgraded design that even had a pouch. but why not do that when I contacted via the regular way? that lowered my respect for them.
I had a different experience. I had a charger that stopped working. When I emailed them they immediately sent a new charger (through Amazon) and didn't even ask me to return the non-functional device. Very fast and excellent service.
