These tests are quick and inexpensive, and help us detect people who have enough virus on board to be contagious. While it is true that they won't detect very low level infections, they will give us a good clue as to who should be allowed to go to the grocery store, or work. The CDC was wrong when they said only symptomatic people should be tested. To control a pandemic that has so many asymptomatic cases you need to test everybody. The goal is to keep people who are contagious from sharing air (or bathrooms) with others. So yes, get the $5 test that's ready in minutes, and use it to decide whether or not you should quarantine yourself. Push your employer and your local governments to get behind wide distribution of this simple technology. It will definitely help.
