Bullet points first, then full review after:
* Lid is air-tight, spout is not
* Pours fine for me
* SMALL, holds 2 Quarts if you fill it up to the absolute rim. Don't expect to be mixing drinks in the pitcher itself.

I wanted to write a review for this product because I think it is a very good product, and absolutely worth the price, but there are a couple caveats that I would have liked to have known first. Like, I assume, most people who stumbled across this product, I needed a jug for holdin' my liquids. I went to Amazon, searched for "Pitcher", sorted by ratings, and not only was this particular product near the top, but it was a brand name I actually recognize, and at a price that was anywhere from 2-4 times CHEAPER than everything else. I scanned the reviews and decided that, at this price point, I can see for myself.

So, here's what I've found.

These things are absolutely solid. Built exactly like any other LocknLock you may already own. This includes the clamps and gasket that holds the lid on... however, there is no such locking mechanism that goes over the pouring spout. It closes, yes, and it'll stay in place, but it's not air tight. If I flip these things upside-down (I bought two) they will both drip out around the spout. So you probably don't want to send a full one of these through the mail, but if you can pack it in a cooler or a backpack where you're relatively certain it's not going to get flipped completely upside-down, you'll be fine.

I read a couple reviews talking about issues with the spout: Difficulty opening or closing it, or problems with the way it pours. I'm not seeing this in either of the pitchers I bought. Due to the hole not being at the very edge of lid, which would probably be impossible with this design, you're not going to get every single last drop out... but it's pretty close. There's maybe like half a teaspoon left at the bottom that I just rinse out when I go to wash it. As long as I don't pour like a crazy person, the flow was completely smooth from when it was filled to the tippy-top until it was empty. That being said, I'd be a little hesitant about putting this in the hands of a child. Although, come to think of it, I'd probably be hesitant of putting any 2 Quarts of spillable stuffs in the hands of a child.

Lastly is the size. As many have pointed out, these fit very easily in the door of my fridge. I can actually put 2 side-by-side if I really shove 'em in there. The rectangular design means they are shorter, thinner, but longer than other pitchers. However this isn't some physics voodoo to add more space by changing the design, these things are just straight-up smaller than other pitchers. Most pitchers, because the spout is built into the side of the pitcher, you tend to leave the top inch to inch and a half empty, and this is typically where the lid rests. Because the spout is built into the lid, and the lid goes over the pitcher instead of into it, the manufacturer apparently saw no need to give this extra space, so filling these things with 2 quarts brings them to the absolute brim.

So what?

Well, my main reason for purchasing these things was that I tend to drink a lot of Crystal Light and other such beverages. Because 2 quarts of water fills up to the absolute brim in these things, it means I can't actually mix said beverages in the pitcher itself, as I would definitely spill everywhere. If I had known this ahead of time I probably would have bought the 3 quart pitchers instead. As it is, I need to mix my drinks elsewhere, and then pour them into these for storin'. Not the end of the world, but a little unforeseen inconvenience I would've liked to have known about ahead of time.

This is my favorite water pitcher. It is compact but still holds a gallon. The lid is easy to lock on and it does not leak. Great price too.

I purchased this product for making and storing Bloody Mary mix to save time when making a drink. But I received it late in summer and rarely drink BM's outside of summer. I ordered two, and I used one for storing milk after opening a waxed paper container from the grocery.

It tends to keep the milk fresher a few days longer.

As a bonus, it's slim profile opens up room in my crowded top refrigerator shelf.

It doesn't leak like some of the waxed cartons do when you bring them home.

Win-win. Win!

I got this for Crystal light for my daughter and it works very well. She can close it up and flip it over over the sink and nothing so coming out. It's easy to mix up the mix. I bought another one for me :)

I bought this pitcher to use, oddly enough, for Crystal Light. When I needed a pitcher, I read the reviews and saw many reviewers are using it for Crystal Light. This is perfect for that. I love the snap lock closures which are super easy to snap and unsnap, unlike some of my containers! They work so easily! The pitcher fits in the refrigerator very nicely. I'm very happy with this pitcher.
