Machine was having issues but the aftersale service was very helpful and they sent a new motherboard at their cost. Now the machine is working normally again. Thanks for the service and support.

Love this V309 tester! It’s super easy to use—4 cylinders let me check injectors quickly, and ultrasonic cleaning works like a charm. 9 test functions cover every scenario I need, and the smart panel lets me tweak settings with one button. 12V/70V/120V voltages fit all my needs, and I can do everything alone. Saves time and gets injectors back in shape fast—worth every penny!

The price is fantastic, and the product quality is outstanding. The online support team was incredibly attentive in resolving my concerns. Feel free to purchase with confidence!! This is undoubtedly the best investment you can make for your workshop.

I put it through all of its functions. We pulled 2 fuel rails from a yard for our stock car. The V309 cleaned, tested each one. The volume cylinders are clear and well lit. The fittings were tight and we had NO leaks. Definitely worth every penny.

I Bought this unit to clean our injectors for our race cars. I have used it a few times and it works great for the price. It has several cleaning options and a ultrasonic cleaner on top. So far so good.

This V309 fuel injector test kit is a godsend for fuel injector enthusiasts! Equipped with four test cylinders and a 1300ml reservoir, it can simultaneously test and clean up to four GDI or standard injectors, saving considerable time. Its ultrasonic cleaning function is impressive—it thoroughly cleans the injectors without causing any damage. The nine test functions cover all the scenarios I need to check injector performance. If you have cleaning needs, I highly recommend it.

I was pleasantly surprised by the cleaning results, they were great. You can test and clean 4 injectors at a time, or just clean fewer if you want to plug other ports on the fuel rail. It’s easy to use and doesn’t take up much space in your garage or shop. Perfect for automotive enthusiasts, entrepreneurs or repair shops to save money and make money. The ultrasonic tank does a great job of breaking down fuel, carbon and dirt. The test unit also removes scale buildup. You can install the injectors with confidence that they will work and flow properly. This is helpful for verifying new injectors and checking the balance between injectors. Or get your old injectors back in tip-top shape. You can observe injection patterns at different pressures and simulated RPMs. It’s definitely a lot of fun in the store.

Recommended, you can visually check if the injector is working properly, and it’s very interesting to test the fluid recovery, very good product!
