are they top-heavy / prone to being knocked over?

not in my experience. They are well balanced and stable. They are pricey but I have several and use them everyday. Work well, good size and minimize damage from spillage.

Slightly when empty, but not so when containing liquid. The size of the container makes it physically impossible to not have some heft at the top. If you are concerned with this issue, buy the 16 oz instead.

No, I wouldn't say that they are top heavy. They don't get knocked over any more than other large glasses.

I have had a Tervis tumbler for a couple years and I haven't had a problem with that at all. I just bought another because I love my first one which looks and works like new!

They rest on the roof. I'm not too worried though. I figure if I keep it within the weight limit, it shouldn't do damage. The weight is distributed among 4 points over the frame. 2014 patriot

They tip over Very easily. We don't have any children, so it's not an issue with us. Hope this helps.

No. They would likely fall. While I like them, I have had clothing occasionally fall off.

No I would not say they are top heavy, I like them a lot. We drink a lot of water and my husband has the blue ones my daughter has the green ones (her favorite color) and I have red ones. I store the clean ones in a plastic box. so they don't fall over.

No this is not made to resist being knocked over. you need to get something more secure from Petsmart that is made for cat and dog food.

I've had no issues putting them on and I've dropped them a few times and no issue. I would describe myself as a bull in a china cabinet when it comes to how gentle I am with things. I would not describe these as fragile, but wouldn't expect them to completely survive a really hard slam on concrete either

Probably not, they are a little top heavy, and dropping them could be costly

Sorry, but in my personal opinion -- no. When they are stacked they are kind of shaky. Not by much, but I would not want to put something heavy on top of them.

I would also say NO! They seem to do a great job stabilizing the front end from sway and bounce, but not heavy duty enough for full weight support.

I would say no as the weight would be too much. They are not that stable to begin with!

I use them indoors right now, but I would think a strong wind would knock them over. Someone else suggested filling them with sand to keep them steady.

Yes, they are. I have not had a problem. I am not sure about the weight but they are heavy enough.

I think so. They can break if smashed but I will use them camping. As for lightweight, yes they are very light.

No, it does not seem top heavy at all - I've never seen it actually tip over during use.

No they don't-they sort of just stack. They do tip over some of you knock them, but they are super fun...

They are not really heavy, but heavy enough they don't tip over easy. I think they are well made.
