Hopkins 10704 FloTool Spill Saver Measu-Funnel

I'm not sure how accurate the measurements are - I assume it includes the volume of the tubing, but they are close enough. It is flexible, and the end cap keeps the last few drops from ending up on the garage floor. I use it to change oil in a generator and a mower.

Pros: Great tool for use on a motorcycle because it measures in both metric and American volumes. Cup has a lid and hose has a plug so that there's no mess between uses.

I tried one of these and found it to be average. It works well as a funnel but not for retaining liquids, as the lid does not seal tight and liquid leaked out of the bottom. Also it would be nice if the flow tube would adapt to a quart oil bottle which would make it much more universal.

Very flexible, just what I needed to get to the filler opening on my Honda snowblower!
