What about their switches? I'm looking at buying a small 10GB SFP switch and TP-Link was one option.

I've already got Ubiquiti kit, and frankly while I don't much like it I can't deny that it works well enough and is reasonably priced for what you get.

So, it looks like I'm going to lean towards the Ubiquiti switches.
