These have held up perfectly for my Kombucha. No explosions and I don't burp! The seals are tight and of good quality.

The funnel was an awesome extra as it sits perfectly and doesn't move like other funnels. As a matter of fact, it's replaced my other kitchen funnels because of it's functionality.

Really nice funnels, big step up in quality from the budget ones you'll find.  Holes are all even and the glazing is smooth.  Did have some issues with order quantity vs. received quantity but Amazon helped me sort all that out of course.  I chalk that up to this being a new item and the seller needed some time to work out the bugs on the listing.

Kit had all the seals I needed and then some. I really liked that they included the temporary hole plugs

Great funnel to use for filling wide mouth Mason jars with dehydrated and freeze dried food.

Works crazy well. I've encountered NO issues with leaking or detection. The funnel was a thoughtful and useful touch. The bottles are easy to rinse out with some mild dishsoap diluted in water. If you're considering it, I would highly recommend.

Because these are so expensive - I didn't want to like this as much as I do...!  It has a great seal on it - better than I thought it would. And while it does have a tight seal - it is easy to flip open unlike another brand I own.  Solid quality - I'm now a fan.

I often transfer different liquids and different solids to bottles, jars, etc, so having a good funnel is essential in my life.  I ordered this set of 3 funnels because they are all different sizes and I figured they would fit different size bottles that have narrow necks so I can fill them up with things like juices, essential oils, organic pest control, etc.

Upon opening the box and seeing these funnels, I was first impressed. These are a really nice and custom build quality, with good quality stainless steel.  Not the "cheap" stuff often used on some funnels I have purchased in the past.  I do like the built-in handle that makes holding the funnel easy.  It also includes a strainer that fits all the different funnels that will allow you to filter out large particulate from going into your desired container.

The aspect of these funnels that I was not expecting was the size of the actual stem of the funnel (the part that you put into the bottle).  Despite these funnels being three distinct sizes, ALL THE STEMS are exactly the same size.  In my opinion, this defeats the purpose of having a set of 3x funnels.  I was expecting funnels with different size stems, so the smaller funnel would fit into a jar with a smaller diameter size opening.  So basically all these funnels fit the same size bottle..  So in my opinion, this is really a set of 1 funnels as the functionality is the same.  Hopefully other products designed in Australia have a more functional and useful design. I was given the opportunity to purchase this product with a discount so I could buy, try and share my opinions with you about this product.

Good quality water bottle. Nice plastic, leak-proof and spill-proof. The autoseal works good and seals tight as well, could be a bit tricky to clean but i just put it in warm water once in a while to kill off bacteria etc. The good thing is the small cap for the autoseal, my old contigo autoseal didn't have that and kept on attracting dust and germs at the place where you drink from. Well constructed and worth the money. Plastic didn't have any weird taste, but my blue one had a sharp aftertaste for like a week but eventually subsided, nothing too bad. I would recommend maybe placing the cap and bottle in some hot water and sterilizing maybe. The handle is tight in one bottle and slightly lose in the other, but works good overall, haven't used it that much. The width of the bottle is a bit wide, but then again it's 32 oz and around a litre so thats  a tradeoff. But with a bit of snuggling got it to fit my swissgear backpack water pocket. Good bottle. Got it for quality. Worth it.

The lids are very tight but I like that they have a good seal. Look very well made. Will definitely buy again.

Works perfectly for what I had in mind...tight seal and pours nicely.

I haven't had a chance to use the funnel yet, but I was very impressed they can individually wrapped. They are the perfect size for the bottles I have and are a great addition to my essential oils supplies.

I am using this can to store gas for my mower. So far it has no leaks and it seals very well. Also I like the push button which is allowing me to control how much gas to fill. No funnel is required to load your mower. The extension is doing great job.

This is a fantastic funnel for filling mason jars! The spout is exactly the right size to fit the mouth of the jar. Well worth the $8 price.

I was so tempted to buy the cheaper funnel but after reading the reviews of the cheaper ones I changed my mind.  I'm glad I did.  This funnel is heavy duty and very nicely made and fits well and is stable in the jar.  You'll only need one of these in your life so why not buy a nice one you'll enjoy using?

I'm getting rid of my glass food storage containers.  It's a pain to always be looking for the exact tight fitting lid.  Many of the lids have cracked over time and render the glass bowl unusable for me.  Instead I have ordered Ball Mason glass jars in different sized (just carefully check for the best price) and will be using these for storing soups and stews in the fridge.  The pint jars are great for taking foods for lunches and best yet, no leaks.
