I did save money, a really significant amount of money.
Obviously, yes, I am capable of going through the work that eliminates my need for this product. I have no trouble configuring Wireguard and setting it up on my client devices and running through all that.
But it was a lot of work to get to this point and I had to spend a lot of time learning how to do that, even as a person who is already technical. Wireguard in particular took me a solid half a day to build understanding and get it configured.
If I was a little bit richer and I went back in time I'd probably just buy all Unifi. Actually if I went back in time I think with my same levels of wealth I'd probably just buy Unifi and save some precious time.
This specific device does seem like a really nice extension of their product line.
