"Slow" loss despite doing everything right? DON'T BE FED UP

I am regularly fed up that I seem to lose weight at a much slower pace than all the metrics suggest should be the case. Like, maybe 2 pounds a month, at a pretty significant deficit (1600 - 1800 calories a day, I'm 5'8" and over 180 pounds) eating high quality foods in good balance, and working out pretty damn hard most days a week - I aim for 45 - 60 mins total, minimum 5 days, including resistance/circuits, intervals and steadier-state cardio.

I'm also nearly 38 and well aware that I have also got a history of not gaining weight very quickly, or at all, either, at times when I think I will - I sense that my body is very committed to its stasis and that as I get older this will just be harder to fight. I don't really struggle with wanting to "blow it all" when I see no scale progress - I like living the way I do, and the food I eat, and the exercise I do - but it can be disheartening!

So over time I've kept track of my measurements to check my progress, and these have definitely been shrinking, and not reflected in the weight loss - I SERIOUSLY recommend you do the same if you have similar experience to mine.

Next, and this isn't a recommendation, but perhaps encouragement, I got myself a body fat composition monitor (with hand grips, about $65 discounted on Amazon, well-recommended model) just to SEE what it would have to say, since I only really care about dropping fat and definitely don't want to lose muscle. On a day-to-day basis the fluctuations (same time and conditions) in measurements seem pretty random, but after using this for 19 days, the thing is telling me that I've dropped just over 3 pounds of fat to my 1.8 pounds of total weight, and put on about .8 pounds of skeletal muscle (which it says it's measuring, as opposed the remainder of your body weight from the fat). This is super encouraging, and to think I'm dropping a little over a pound of fat a week is really all I wanted to know.

Since I don't fully trust the device, I am not really recommending it, but it's very encouraging to me this morning, and I hear other people out there groaning about very slow weight loss, too. So if that's you: really truly "doing everything right" and really not seeing a lot of scale movement (but presumably inch loss) - maybe you'll find a little encouragement in my experience as well, and it might be worth getting something like this in case it gives you similarly encouraging results...
