I dumped the "slime" out of the supplied bottle and found that the air compressor works fine with the empty bottle. That way I don't ruin my TPMS. I also went out and bought a scissor jack, a tire plug kit, appropriate socket and a breaker bar. I also carry tools to remove screw/nail should it remain in the tire. Later on, because I was bored, I "modified" the supplied air compressor to work without the empty bottle. On top of all that, later on I purchased an air compressor from Lowes to replace the one that came with the iQ and now I carry the iQ "modified" iQ air compressor with me when I go on my motorcycle rides.
