It's good for the price
Pros: For what you pay, you get quite a bit. I was specifically looking for 801.q VLAN tagging and LACP, both of which it has and does well. I did not notice any noise from this switch. It normally sits in a space with three HP N40L Microservers, so it's possible that they drown it out. However, I've had it in the living room a couple of times for troubleshooting purposes, and I don't recall any obnoxious noises.
Cons: Ports shut off on this switch, seemingly at random, and won't come back on until you power-cycle the unit. The logs give no indication of why it shut them off. Then, sometimes, they don't come back. I bought my first GS716T in 2012. In the first year, it blew a port. I got it replaced under warranty, which was actually not that painful. Now, less than a year later, my replacement has also blown a port. With the advanced replacement warranty, it's not horrible. However, taking a couple of hours here and there to go through a replacement process isn't exactly trivial either. Depending on how much value you place on your time, you might want to consider a higher-quality switch. It will cost you more, but might be worth it.
Skip It
Pros: Cheap.
Cons: This thing worked OK for about a month, but never better than OK. It gradually got worse. Now, it can handle ping traffic, but nothing heavier than that. It likes to show you a 300 Mbps connection rate, but actual data passage is never higher than 20 Mbps (measured with iperf) under any circumstances and will frequently drop to under 300kbps. I brought my old Actiontec DSL modem's crummy 802.11g wireless back online to compare it to this, and it performed far better under the same conditions than this thing did.
Horrible Performance
Pros: Setup is really easy. You can even configure it from a wireless connection right out of the box. If you're just doing basic Internet browsing without any local network file-sharing or streaming needs and don't want to have to follow a lot of directions, this device is probably OK.
Cons: Wireless performance is comparable to an 80211.b-only system. I tested with iperf using both wireless-to-wireless and wired-to-wired. The 2.4GHz network occasionally breaks 20Mbps but not for any amount of time. The 5GHz network is really spotty, but never exceeds 200Mbps. Tested under a variety of distances and conditions. It can get worse, but it can't get better. I have a four year old G-only ActionTec that outperforms this device in every metric under the same conditions. Even wireless-to-wireless was better, which it shouldn't be because the ActionTec isn't MIMO.
Overall Review: I've been on the hunt for a device that will handle the wireless portion of my network so I can just use my four year old ActionTec to handle my DSL uplink, as we're doing media streaming and G just doesn't cut it. Linksys is the third vendor I've looked to, and has been the worst of the three. Where the other manufacturers' devices at least performed adequately for a few weeks, performance with this device was horrible right out of the box. I'm still looking for a wireless router manufacturer that isn't just phoning it in. That vendor is clearly not Linksys.
