Not really sure I recommend the travel espro since it holds such a small volume; unless you make a stronger ratio...
I have the travel Espro as well. I bought it as a "12 ounce" press without taking the time to read more carefully. It actually makes a much smaller volume, maybe 8-9oz. I was routinely overfilling mine and causing a mess, trying to get a larger amount out of it.
So now I usually do two things: First, I use more coffee and then dilute the result with hot water. Second, I do the little trick where, after plunging, you carefully pull the plunger up again partway, invert the press, and then press the plunger again. This has the effect of forcing out most of the residual coffee. You do get a bit of fine silt that way too, though.
As a travel mug I found it unpleasant to drink out of and too small an amount to bother carrying around. So for me it's just a small press. I'd rather have a larger one but I'm not going to spend what it costs for one of the larger Espros. Of course one can get clean results with a regular press simply by waiting a bit longer. James Hoffman did a video on that.
