I have had basically no issues with my setup: Edgerouter 4 (overkill, had a lower end Edgerouter earlier with no issues except the power adapter died, other hardware was fine). Some pretty basic unifi AP. As well as some cheap dumb gigabit switches. Can basically fire and forget them. Relatively easy to do most things I need on it. Never needed a reboot outside of upgrades. No stability issues, unlike basically all other home grade all in one stuff I have experienced in the past.
I have never ordered something from Amazon. It was introduced in my country a few years back, but it isn’t really that good of a site (at least the few times I have visited it).
Like many here, I do not want to support a monopolistic company like Amazon. Luckily I live in a country where I have better options. I tend to buy things from plenty of well rated sites. Environmentally conscious sites if I can.
I could see myself buying from them if there genuinely isn’t another option and it is something I really need, but that has yet to happen.
