The Zyxel MG-105? I use that switch as well.I paid £70 for a Zyxel 5-Port 2.5G Multi-Gigabit Unmanaged Switch a year ago and it's been faultless. With the pace that things are moving on, I expect you can get better now, but my motherboards only have 2.5gig ports on them, and I have little need for a 10gig switch at the moment.
They'll be the same chips that the more expensive switches use, there might be cheaper magnetics on them and a really rough power supply and AC adapter that will borderline kill you. If I was buying AliExpress stuff or the equivalent six-letter made up brand that has made it to Amazon I'd at least want something that had a USB-C power input so I could use my own power supply for it. Something sourced in China for £2 that weighs 50g shouldn't be plugged into the mains, best case scenario is the glue holding it together fails and you end up with live parts exposed on your wall ready for your child to run into.
Have the same QNAP here at home also. Got it before these cheaper ones took off, but I also wanted something that's been out longer so any existing issues would have been more known about and solutions or options for solutions are available to go for if needed (including RMA). Hence I took the QNAP.Say what you really mean
Although I have to agree, I wouldn't want them either at home or at work just for the sake of saving a few quid.
Personally I'm using the Qnap QSW-2104-2T at work and it's been flawless
