Got new topsider today and somewhat disappointed by the result. I assembled them together as per instruction, place the plastic tube in oil (dipstick) tube of warm engine but took five attempts to completely drain the oil.

I had to initially pump 25 times to pressurize the cannister, release the plastic clip and the suction starts working. However, after 30 minutes the suction stopped working, I again pumped 15times and waited for another 20minutes. And since it's not empty still, another 15times then another. I also had to restart the engine in between to keep it warm.

It seems that topsider IMHO is pure hype, not worth the effort. I would not recommend this poorly designed product to anyone. The concept is good but the result isn't.
