Which switch brands to stay away from?

Hello all,

I’m looking for a reliable, unmanaged 16-port Gbe switch. I know it’s a wide range, any brands with a history of problems? What do you guys like?

It’s going into a school with about 20 wifi devices per port, using 6 ports total. Not much data pumping through, mostly cell phone web research or laptops using office, maybe teacher chromecasting some youtube video.

Now that I write this out, should I be concerned with uplink bottleneck??
