Allstar Performance ALL40108: Efficient 1 Pint Funnel with Extension - Streamline Your Fluid Transfer Process! Review

Used for flushing gear oil. It worked, but the lip is so flat in the stuffing tube that it was very inconvenient and caused some spatter. I'm not a pro so I'm sure some clumsiness is entirely my own. But a deeper lip on that narrower bottom edge would make a world of difference.

The only thing I can complain about is that it seems very expensive for what it does. The funnel can be unscrewed from the flexible part. The flexible part is small enough to fit in tight spaces. Probably not flexible enough for sidefill gears but perfect for top fill plugs in crowded areas.

I would give it 5 stars, but as other reviewers point out, it's not designed for heavy use. It creaked because it was on my shelf and it was jammed. However, with a bit of duct tape I got back to business and it fitted nicely and did the job of routing the diff fluid into the tiny hole "deep there and around the bend". I've had it for a long time!

The black part of the funnel (tube) is very small. this is normal most of the time, especially since I pour oil through the dipstick hole on a Subaru. Though it's no fun when it comes to thick gear oil. It will take some time. I only gave it 3 stars because the tubing itself is cut to flex every 2 inches or so. I wish my old funnel was flexible throughout, but it works, but the funnel (red part) isn't very stiff either.

Funnel arrived with extension attached (requires longer box than needed; consider). It took me a minute and looked at the image on the product page again to see that the tapered end of the extension was not properly inserted into the funnel. In fact, there are currents on the funnel and expansion; the latter is screwed onto the former. The fit is fairly snug (having started, I have to use pliers to screw it all the way in) and it's a somewhat malleable plastic, so be careful not to damage the…
