*** I am not the most knowledgeable in how the internet, wifi, ports, etc., all work.  I'd say I'm average on the router/modem connection knowledge scale, lol.***
First, I purchased my Netduma R2 almost a year ago now. I'm on Xbox and was playing on wifi..(I KNOW ). I finally called my ISP out to set up a direct plug-in at my new spot, with 500gbs up and down. It was night and day. I still wanted as much performance as possible, so I ordered the dumaR2 after a friend of mine told me about it. Many people I see on the forum have acquired it for the geo-filter, which is insanely impressive. If I even knew what that was when I got mine, I would have probably purchased it if that was the sole function.  
However, my favorite things are the control you have when you log into DumaOS; it's nuts. You can run tests and mess around with numbers till you get the best connection possible. You can allocate bandwidth in QoS for specific devices, set congestion control to limit other devices taking up bandwidth. Check the Network Monitor to see what devices are active and taking up space.  Again, this is just the tip of the iceberg, and I still have a lot to learn. 
The only things I complain about, which are very small and wouldn't justify not getting one, are that sometimes the RAPP doesn't load when I log into DumaOS. I reboot the router from the website and reload OS, and it works perfectly. (I'm sure I can do something to prevent that, like clearing my browser, etc., my way seems to do the trick.)
I'll never go back to any router even if the "dark day" comes and I never play video games again. I can switch my setting for work since I'm always on my laptop on skype, zoom, etc. 
I hope you get/gotten one yourself!
