This product worked very well for my needs. It was very easy to use and set up. All you need to do is follow the instruction and you will be ok. I have read a few negative reviews on the websites; however, I find these people’s reviews wrong. Once you have it all set properly you won't have any issues. I did two cars and cleaned the injectors with no issues. For DIY home use it’s great, I know you won’t be using it every day, so it should be fine. Great price and quick shipping, how can you beat this. I recommend this product to anyone looking to buy one.
