[meh]I didn't have any issues before I installed it, and it didn't create any issues, so I guess "I like it". [/meh]
For keeping the track clean it seems like a good system. I think I will use it to pull a vacuum on my radiator overflow next season hoping that it will draw coolant out of the bottle and vapor it off in the exhaust if I lift the head again. (at the very least I need to run a larger coolant bottle with a larger vent and a different internal design to prevent external leakage but that will be a discussion for a later date)
