Not anti the kit as its better than doing nothing and for some getting under is difficult (I am getting that way as the other knee is giving out).
I'm with you on this, Colin. Not only knees, but recently when getting up after lying under the car I have suffered dizziness and Mrs St Eve has banned me from doing it. So the remote greasing kit I have is a real help. And, as you say, 2 or 3 pumps on each point does it.
