Do these bottles leak if they tip over? How sturdy are the lids / straws? Thanks!

They do not leak one bit. The lids are sturdy. They are not straws but openings and are large and perfect for smoothies.

They Don't leak... But you need to make sure you "snap" the lid close. if you don't hear the "snap" its not closed. :-)

As long as the lid is secured it does not leak, it is very sturdy and it do not come with a straw

These bottles do not leak if they tip over. They are very sturdy. They do not come with straws. We are very happy with this purchase.

No leaking if lid is screwed on. The pop-up white lids aren't straws; they just open-up drinking holes. And they are very sturdy.

I've had no leaks. I carry one in my bag ever morning and no leaks. They are super sturdy lids, they snap closed really tightly. Does not come with a straw. Highly recommend them.

As long as you close the lid they do not leak. The straw fits in the lift tab I do have a problem closing and opening the lift tab because I have arthritis and I'm old, a normal person would have no problem.

I have not had any issues. I've even put them in the dishwasher and the lids still fit snug.

No they don't leak, they work really good mix your protein powder without leaving clumps

Yes and no. Yes if it's a liquid like water and only very little leakage. Maybe one or two drops of liquid just from the act of it tipping over. If you are drinking smoothies, they will not leak at all.

We haven't had any leaking. But in the tipsy hands of my two year old it will spill out the top if the lid is off. :) we enjoy them outside!

I have never had them leak and I've been using them for a year now. I've put fruit in them and the juice has never leaked. I own 3 sets of these containers and love them! Now that my son is getting bigger, I wish they made them in a bigger size.

Yes they are leak proof. I bought mine in the Container store and it is labeled leakproof on their shelf. The store sells the 2 oz size for $1.95. I use it to carry my oily lite salad dressing to the restaurant with me and it has never leaked.

I tested two of them to see if they are water-tight. You have to have the lid perfectly in place, otherwise they leak. I would not recommend them for transporting liquids (such as in a bag). Hwvr, they would make fine canisters for around your work space.

I have not had any problems with mine... Sometimes if you do not line up the bottom right when you screw them on they will leak (just like anything with a screw cap). What I noticed is that water can get stuck in the bottom (Between the white "ring" and the bottle plastic) and it seems like the bottle is leaking but its not.

I haven't experienced leaks with them, you can place them horizontal and assuming you have a flat even surface they'll be fine, but I own these and the 5 ounce medela bottles that are fatter and I prefer those.While they haven't broken on me I feel like these are more flemsy and I can't store as much milk so I've switched to the larger ones.

I have two of the 8-oz and one of the 40-oz of these bottles and none leak. All the lids have rubber gaskets on them. I use the small ones in my daughter's lunch box. It looks like they've changed the lid design since I bought mine about 2 years ago. I can say that I've found the quality of their bottles to be excellent.

Yes and no. I emptied out one of mine just now (the smallest one), filled it with water, and shook it fairly vigorously. In that case, it leaked somewhat. However, unless you really make an effort to cause leakage, spillage, I believe they would be fine. Sorry it took so long to respond! (Just saw the previous response; I believe I agree, in essence, though I think if you had one in a box or other container, AND didn't go through an earthquake (or similar), it would likely be "okay." Tupperware? might be better, or something similar.

Yes, they are screw on caps and do not leak if on tight. I take one to school everyday. I stick it in the pocket on the side of my book bag. I throw my bag in the car. They never leak. I put the bottles and lids in the dishwasher. I love them. I have three sets.

The straw lid does leak. It is really designed to be upright. It's the one downside.

No they do not. I had wanted a bottle with a straw, but decided to go for these. I have their old ones with straws but over time the straw is getting harder and harder to work. This one is easy to use and doesn't leak if it tips over, the one with the straw did if you didn't have it closed. This one is very insulated and stays cold for long periods of time, especially if you use ice.

These are leak-proof. I've packed water and milk in them for the kids' lunches and never had an issue. (Except when the preschooler threw his away and I had to dumpster dive.)

I never had an issue with them leaking and I used them everyday for six months. The only problem would be if they are overly full then frozen, the top won't stay on then. Just don't fill to the very top.

We only ever use the straw valve and the straw, but I only give my daughter water in these so I don't worry too much about leaking. They will leak out if tipped upside down, but I still really love these sippy cups and we never leave the house without one.

The lid snaps down and should not leak. (Haven't tried it, though a bucket with guck in it shouldn't tip over.)
