Injector Cleaning Tool Experience

[madtownZ4]

Has anyone used a product like this to clean fuel injectors?
If so, what liquid did you use?
Any before and after comments?

I know removing injectors and cleaning would be better, but this looks pretty easy and I could use it on my other cars. I know you can add products to the gas tank as well. I am hoping to get feedback on this approach. Either DIY or service by a shop.

Here is a video I found.

I have a new to me 2005 Z4 3.0i with 140K Miles on it. I am thinking about paying a mechanic for this service or possibly purchasing a tool and trying myself.....

I would wouldn’t bother with that machine.
Best to take them to an injection specialist to have them tested and cleaned.
