Question: Can you get your hand inside to clean it? Or how large is the cap on top?
Document: I just love this bottle. After our move, I'm buying another to keep on hand. Easy to clean and perfect size for the top fridge shelf. Also, it is BPA safe.
This 2 gallon water jug works very well. It is too big to fit into a mini fridge but as I make a lot of hot tea so that is no big deal. The top opening is large enough to clean easily, however, some parts of the jug (the handle) cannot be cleaned as easily. However, I have no complaints so far.
Eventually the valve will let some air inside but causes the liquids to pour out very slowly.What I had done to alleviate this, I made a small pinhole in the lid. Not big enough to cause too much fridge air to get in, or cause liquids to spill out if unit is being shaken while being handled to be put back in the fridge, etc.This allows a constant stream of liquid pouring out the spout.
I like the convenience of this refrigerator bottle.Seems to be made fairly solid. I gave it a 4instead of a 5 because, after it is half empty,you have to loosen cap to make water comes out.Do not leave the cap loose, because youwill get a funny taste from food in the refrigerator.
The picture here is misleading. The item is about 13.5" deep x 6.5" wide x 9" tall. It doesn't fit in the space I have despite a good guess from the picture that it would. It's way deeper that picture indicates. Also, the cap is a ridiculously poor design. To make a seal there is a plastic disc in the top of the cap. When you loosen the cap to let the air in, the disc stays in place on the opening mouth and blocks the air off anyway.
As most other reviewers said, the spout does leak lightly.Not excessive, but enough to cause a mess in the fridge.I use this to store iced tea in the fridge. it drips slowly at the spout. Probably the valve inside is defective.I just have a paper towel at the bottom of the fridge inside where the drops end up so it's ok. I remove it once a week or so and replace it with a new paper towel piece so the drips don't make a mess.One other issue was there is no way to get air inside, so when pouring out liquids will go slower and slower until you let some air go inside.
This works just liked described. The two things that I don't like about it is one, the flow is really slow (even with the top off); and two, at least 2 cups are always left in the bottom and it's really hard to get all the liquid out (even through the top).
Now they don't carry them any more at the grocery and I can't find them anywhere else, so I had to try this one. I'm moving on now.I will say that the spigot did NOT leak on mine. The instruction sheet they included was all about how to make sure the spigot seals were in properly and what to do if it leaks. Also it came fully assembled, so you can't put it together wrong, which I suspect was happening. I think they have sufficiently addressed that one. Now if they would just fix the cap and the depth.
Everything as expected: shipping, size, ability to handle hot tea. It is a little hard to clean because soap and water may leave it clean but smelling like sour milk smell after two days in the fridge. Doesn't change taste. You will need to prop it up on the end to make it empty all the way. Sounds obvious but the picture looks like the spout is lower than it is. All-in-all love it anyway.
Simple and clear instructions are enclosed within the bottle when you receive it.The negative review stating the operator complained the product is defective when after a quart of liquid was left in the bottle it came out very slowly then not at all is nonsense. Again read the instructions. It clearly states to loosen the cap and liner to permit air to enter replacing the liquid being drawn out thus not forming a vacuum. Very simple!When assembling the spout pay attention to the instructions noting that the two washers have a flat side and round side.
Answer: The opening is large enough for a normal size hand to enter.  Nothing to cleaning them though.
