I did not know my dampers had so much air left in them before I started to use this tool today.
I am pretty thorough regarding getting air out the traditional way so this was an eye opener for sure.
This is the best tool at $32 I have spend this year.
This is a very essential tool for damper maintenance. I refill all four damper at once and this tool can remove air bubbles from the four dampers effectively and fast. I recommended this tool to RC hobbyist who have plenty car models, on road cars and even off road cars.
