Anyone using an ultrasonic injector tester/cleaner combo?

Has anyone here worked with those injector tester + ultrasonic cleaner combo units? We’re getting more cars with rough idle and poor fuel delivery, and removing injectors just to guess isn’t helping. Considering a compact bench machine that can test spray patterns and then clean injectors right away. Are these worth it, or do they end up sitting unused?

Injector tester/cleaner units can make a big difference when you deal with misfires, rough idle, or poor fuel delivery on a regular basis. Being able to see the spray pattern, flow rate, and response of each injector removes a lot of guesswork from diagnostics. After testing, the ultrasonic cleaning cycle often restores clogged injectors without the need to replace them, which saves both time and money for the workshop and the customer. For mechanics who want a compact and straightforward solution, ECUTools offers injector tester/cleaner units that are easy to operate, well-built, and suitable for everyday shop use  ecutools.eu/ Their machines come with clear controls and practical accessories, making the whole process simple even for those who haven’t used such equipment before.
