Will get the job done...  Until it doesn't.

The funnel itself is just fine, but the extension hose is cheap, thin, non-durable plastic and I don't see it lasting more than a year or so.

There are MUCH better funnel sets available.

Be cautions.  This is a cheap, generic Chinese made item that dozens on Amazon sell.  Shop carefully.

Well-designed, works well, easy to install.  Hope plastic nut doesn't wear down over time, but probably not an issue given the top-filling design.  Finish is a bit shinier than expected, but matches ORB finish well.

UPDATE:  as with numerous other reviewers, this unit suddenly stops working.  Clean it out and it pumps for just long enough to have you believe you've fixed it - but wait a minute and it fails again.  Too bad; it held such promise.

This is a decent sharpener but it doesn't last. It has a tendency to stick or jam on occasion, which can be annoying....And after six months, it seems to be reaching the end of it's life. You get what you pay for...if you want a really good, heavy duty sharpener that eats through wood with no sticking or jamming, invest in one that is twice the price of this one.

Does the job, but after a year or so, it wears down.  I have to replace it more often that I think I should.

Not inspiring quality, but great price and gets the job done.

It isn't the best constructed case, but it'll probably last until it gets dirty enough that I would replace it anyway. It's about what one would expect at this price-point.

Gets the job done but I doubt it will last long. The plastic locking clips are cheap and flimsy and the batteries sit very loosely in the case before the lid is closed. If you're not careful you'll spill all 12 batteries before you close the lid. Speaking of which, after loading it up the lid is very hard to close as it doesn't line up perfectly. Altogether I think this thing will last about a dozen times opening and closing before it breaks and I throw it away.
