Expensive for what you get.
I can't help but marvel at the cost of this attachment. It's just what it looks like in the picture an extension hose and several extension tips. The tips seem to squeeze into tight places and direct the fluid in the correct direction. Considering that you'd use this device very rarely and you likely only use a single piece of this device, a single tip, unless this is made out of high grade Platinum or titanium the price point does not make sense. There are other spray bottle options available with tips and attachments for about $35 on Amazon. I compared this spray tip with LiquiMolly spray bottle against the other spray bottle and attachment option and they spray about the same. The only difference is if you have to squeeze into very tight spaces. I've seen videos where people make their own tips out of thin tip copper. For the price that might be a better option. If you are a professional shop looking to do DPF cleanings regularly then this may be an investment worth making. Yet for the DIY mechanic I couldn't justify this cost.

Buena herramienta.
Esta herramienta también es muy importante, la recibí en buen estado pero incompleta. Faltaba la tuerca para ajustar las agujas o el aditamento por donde sale el líquido, no lo devolví porque poseía una similar en mi casa, de viejas conecciones hidráulicas del baño.

LiquiMoly DPF Spray Nozzle
Spray Nozzle for cleaning DPF worked well... or as good as I could see without removing the DPF. Price was a tad high considering the Spray Gun was not included however that piece was expensive too. All together, I was in over $300 for the Spray Gun and Spray Nozzle. The cleaning solutions were another separate charge. I know I will be using this as a DIY service but $300+ seems high for a DIY tool. I still needed it so over time I intend to get a lot of use from it. The product itself is well made. After using it a few times, the product is holding up to the use and nozzle attachments are perfect for getting the cleaning solution going in the right direction. I rated it as 4 stars due to price but it is a good tool.
