This fuel injector cleaner/tester works well right out of the box. Ultrasonic cleaner is fairly large at around 1200 ml and has decent depth for cleaning a variety of parts. It is not heated, though. I used the A-Team Ultrasonic Carburetor Cleaner from Amazon as a cleaning solution and used Isopropyl alcohol at 92% for the test fluid. Cleaned and tested 8 injectors first day taking 4 at a time through each test. Several injectors were bad to start so I ran through several ultrasonic cleaning cycles, removed the screens, and reverse flushed before testing. What's really nice is the number of fittings supplied with this set. In this case, the fittings for reverse flush were a different than size than for testing. While this accommodates injectors of various voltages, it also allows you to adjust the pressure to your operational needs. The results were an awesome aerated spray pattern on each with similar flows across all injectors (within 2ml). One thing to note is never use anything corrosive as a test fluid as it will destroy the pump and seals very quickly. The manufacturer recommended the alcohol which worked well for me especially since test fluid is difficult to actually procure. If you can find it, it tends to be very expensive. If using on injectors for every day drivers, alcohol as a test fluid is fine.
