### ⭐⭐⭐⭐⭐ Well worth it!
*by J***N on February 19, 2024*

Bought this to clean out injectors on my 1.5l tubro engine build!Used ultrasonic fluid in Autools easy to use ultrasonic cleaner, and the miles of carbon build up came right off! Was then able to test the injectors in the test tubes and it was very easy to hook the wires up to the injector and click start! Easy as that, would highly recommend , no issues

### ⭐ Dont waste your money
*by H***. on May 14, 2023*

Had hie hopes for this but I got somebody else trouble. When I opened it there was rust in the ultrasonic tank but I could have lived with that I could have lived with the fact that it was missing the valves to empty it with so I went to town and bought to shut off valves got ready to use ot and some kind of trash in glass tubes by then I am getting aggregated then I start it up the pump only works at times and yes I know how to work it . I bought $200 worth of cleaning and test fluid for it . The only hood thing I can say is the ultrasonic cleaner worked really really good but the rest of this was not a good product. It was actually atrocious and I have never wrote a bad review and I really hated to but I despised the fact that the unit I recieved was most likely something someone else returned. Very disappointed I had big plans for my saterday afternoon and they were wrecked by this machine. Now I have to drive 45 minutes to return it to a ups store and apparently wait 10 to 17 days for a refund . I am very disappointed in amazon for this. Totally not right. Maybe some lucky people get a good one but I certainly didnt.
