I love having the flip lid because sometimes it's nice not to have a straw and it's easy to close up if carrying in a bag or back pack.

I like it. Only wish it had a flip top lid. Only real downfall.

I'm happy having these but can't recommend them because the latches flop open so easily. The colors and size are nice, and so is the handle but you need to be careful carrying by the handle because of the floppy latches.

I've been saying that a certain company needed to come out with a lid like this for months because being able to close the lid with kids is amazing. My husband has actually stolen this lid from me and has taken it to work. He loves it. It fits nicely on to an 20 oz Yeti cup (and probably and similar companies). I would recommend every few day taking the black part off to wash with warm water and soap because if not mold will build up. I found out that the hard way and that's why I'm giving it only 4 stars.

I have had one of these for the past year and loved the fact that it was glass rather than plastic.  I didn't have any issues with smells/mold.
I accidentally dropped my last one outdoors on a cold day on the cement and it shattered.  Bummer!  If you drop it just wrong and the glass hits the ground it'll break.  I got another one, but have decided there's one thing I don't like about the bottle- the lid.  The flip top cap is fine, but it is soooo easy to cross-thread the lid on after filling it up, so the second that you do, you look like a fool because you just leaked water all over yourself since you have to tip it upside down.

I use this everyday and I really like it - love the smaller size and that it's easy to clean. My only complaint is that the mouth piece can be a little difficult to open at times, and I've had it splash out when I did finally get it open. BUT at least I can be confident that it won't spill if it tips over or if I put it in my bag, and THAT I do like :)

Love the idea and I feel better having it on me for emergencies but I wish it flipped up easier.

I love the neumatic mechanism which lowers the lid slowly preventing it from slamming shut.  The 4 stars comes from some warping of either the lid or shell which causes the lid to not form a good seal on the container.  It's fairly substantial, so the trash was smelly then it wouldn't contain it too well.

I would never think that I would love a lid so much.  If you own the Anova, you'll love how the hole just fits the cooker perfectly.  It is quite easy to take on and off while the unit is running.

The cover keeps the water level fairly constant.  This is invaluable when doing long sous vide cooks such as a pork shoulder.  You also don't have to worry about random bugs or dust getting in the water during cooking.

I never wanted to be one of "those" people -- the ones who carried water with them everywhere, like a baby bottle, as if there is some need to never go more than ten minutes without a drink. But I have to admit -- it's handy. I especially like having one in the car.

I like steel bottles because they are clean and add no flavor. But I don't like it when the water gets warm and in the summer, leaving the bottle in the car means hot drinking water. Yuk. So I wondered, there must be insulated bottles and sure enough found this one.

Love it.

It's a bit smaller than most, which I like (carrying 22 ounces of water or more around seems silly to me).

The insulation works great. After three hours in a hot car, the water is still pleasantly cool.

The spout is handy and flips open easily. It doesn't leak at all.

This twist top lid is very easy to get off to fill and wash, and secures just as easily. I was wishing this was a bit bigger, but it does hold twenty five cups of coffee. That's big enough to host that meeting or baby shower, etc. The stainless steel is easy clean and durable. It also just looks nice. Easy set up and directions. I also love that you can keep it warm, as well as set up the auto shut off as a safety feature. The plastic handle on the spout does worry me a bit. I know some guys who don't know their own strength and tend to break things like that. Time will tell how that holds up under their bumbling. Other than that, it looks and works perfect. It has nice carrying handles and isn't so terribly large that one person can't carry it around, even when full. The water level marker guide helps you fill it to the desired mark, and keep an eye on how much you have left. I'm not sure if the plastic coffee basket can be put in the dishwasher. For now, I'm hand washing everything.

I love the design of this thing. I really like how the lid fits snuggly into the tea infuser. I got this because it was a good medium size for if you wanted to just brew some tea for yourself and/or use for some entertaining.

HOWEVER, be warned that when that lid is on the infuser, it is REALLY easy for the two of them to just fall right out when you are pouring (if you are steeping something for that long).

The good news is that the lid also fits snuggly if you take the infuser out.

I love the lid that covers the screen.  I no longer make accidental calls when I put it in my pants pocket.  However, the lid does not stay shut when I lay the phone down on the desk.  The stiffness of the "hinge" makes it flip open.  Otherwise, it serves my purpose.

Love the concept but sometimes if lid isn't on exactly right, water spills out and I have to start over.

This is a great idea but the issue I am having is with the lid staying on, so I give this 4 stars.  I do like that its small, doesnt take up a lot of space and is perfect for the small stuff I use to stick in the door pocket until I get home. It is also covered (sometimes).

I want a closeable lid, otherwise I love this cup!

I was thrilled this fits the top of my 24oz and 12 oz wide/short cup and the 16oz tumbler too.  You know it's a good seal because the top burps like a Tupperware container.  I dumped my cup upside down and it leaked out the straw hole (with another brand of reusable straw in it), but the top stayed on even with vigorous shaking.  So don't expect it to be a miracle sippy cup replacement, but for preventing disastrous spills, it should do the trick.  I like the rubbery feel of it and the way it holds the straw nicely without any plastic clacking noise (I stick a metal straw in the top of my Tervis sippy top, usually, for my endless drives around town taking my kids place, and it's not quite as sealed or silent as I'd like it to be).
Anyway, two thumbs up, thanks for a nifty product, GreenPaxx!
