Question: I store cooled fryer oil in gal milk jugs. Milk jug opening is too small for funnel.  What are others using for containers?
Document: Well built and the screen fits nicely inside of it. You can tell its not a cheaply made funnel by the overall construction, and the price.Amazon fails to mention this, but this funnel goes from 11 cm to 4 cm.I used mine for straining oil back into a storage container, but it won't fit into the opening of the bottle I have. So I'll be looking for another bottle to store my oil in for now.
Obviously, I am very impressed with the quality of this funnel/strainer. It is very good 18/10 stainless steel. The shape and balance of the funnel is superb. The strainer not only fits perfectly but is a fine mesh that will "trap" even small particles. I use mine for re-cycling high-quality frying oil (safflower). My savings for using this funnel/strainer far outweighs the cost of this item. You get what you pay for !
I bought this little beauty to filter my deep fryer oil.It is easy to clean,store and works like a dream. I am very pleased with it's flawless construction. A very good choice.
OK why did I buy this? Long story made short. I bought a Butterball Turkey fryer, wanted a funnel type strainer for filtering my oil after frying  ( peanut oil can be re used 3-4 times  in 2-3 months  ( after that trash it ))  All fine mesh strainers I could find were for tea and quite small.
This funnel is made very sturdy - it will definitely last several life times! I've used it to strain the oil in my deep fryer so I can get a few more uses out of it and save money. It's great for straining out the small seeds of berry fruit jams and juices. It's also great for pouring thicker sauces into a wide mouth, squeezable 16oz condiment bottle - mayo based sauces don't pour like a liquid and are too thick for the smaller funnels to pass through the funnel chamber.
This is the greatest strainer I've used to date. I use it to strain the oil from my fryer. The strainer fits perfectly into the top of the gallon container that the oil came in. Works quickly and the filter/screen catches all the small particles.
This is a very nice funnel. It says it's for jam which I never knew you used a strainer for jam - sorry I got side tracked. This is very well made heavy duty steel and a nice steel mesh strainer. I think it will work great for animal milking and pouring into a ball jar - which is what I'll be doing. The opening is small - but not too small -will work nicely. I measure the opening at the bottom at 1 1/2 inches in diameter.
I own a small jam business and use purchased this funnel because the jars I use have a small neck. This funnel is superior quality to any I've seen in stores. I really debated on spending this much on a funnel, but haven't given it a second thought since using it. Wish I had bought this funnel a long time ago. Screen is a nice feature. I use it when I am pouring jellies and it catches any bubbles or foam that I missed in the skimming process.
Bought to filter and re-cycle cooking oil for our deep frying. I was hesitant at first in that I wanted a dishwasher safe funnel but one that would fit the opening of a quart cooking oil bottle and not take all day filling the bottle as most kitchen funnels do (they have any ware from a 1/4&#34; to 3/8&#34; opening).
I bought this funnel so I could strain my Lou Ana peanut oil. The problem is that the funnel sits just outside the opening so when you pour the oil back in you have a light film of oil that leaks down the side. The strainer itself is excellent as it catches even the smallest particles. So, I decided to keep the strainer and go down to Auto-Zone and buy a $2 dollar funnel for it.
Answer: I am using glass mason jars - the funnel fits quite well no matter what the size.
