### ⭐⭐⭐⭐⭐ Perfect replacement
*by K***N on 17 July 2019*

The other top for my bottle had become mouldy on the rubber seal, so bought this as a replacement. As expected.

### ⭐⭐⭐⭐⭐ Perfect
*by H***D on 11 April 2021*

I have a litre bottle with a non spout lid and wanted to use the bottle on my desk at home. This lid fits perfectly, and if my cat jumps up on my desk I won't have to mop up a spilt drink.

### ⭐⭐⭐⭐⭐ Very nice lid. If you need a replacement, give them a try, but I'm not sure if it's worth the cost to upgrade outright.
*by J***F on 24 August 2014*

I partially freeze my water bottles for the day over night, and every so often I accidentally leave one in there. When that happens, occasionally the bottle itself will crack, but more often than not, the threads on the lid just get shredded up and the cap bursts off, so I end up replacing a lid a month or so. when I saw that these were something like $1.50 more, I decided to give them a shot. Here's a few quick pieces of info for future buyers. Pros: -The spout is great. I always get the large mouth nalgenes because it's easier to throw lemon slices in there if I want, and it's much easier for cleaning, but the big mouth can be awkward. This is a pretty good compromise. The spout is about the size of a glass soda bottle (probably a little thinner) and very comfortable to drink out of, but removes for cleaning. -These seem way sturdier than I expected. Nalgene always makes nearly indestructible products, so I don't know why I was surprised, but something about the design seems . . .tenuous. I can assure you, it's not. This is a very substantial product. We'll see how it survives a fall if I mishandle it rock climbing, but for day to day use, I have no doubt that this would survive a fall from head height. -The lid closes with both a plastic catch/push button on the front, and a wire swing gate. This thing is not coming open by accident. My guess is that it would break before it opened in a drop. -I've hung it by a carabiner and attached it to my bike already and it doesn't seem any worse for wear. The loop is definitely handle worthy. -The closing mechanism is a little stiff to provide a solid seal, but I have absolute confidence that there won't be any leaks or drips. Cons: -This obviously adds to the height of the nalgene. It's not much, but it just so happens to be just enough to make it catch on the zipper on my messenger bag, so I'm sure I'm noticing it way more than anyone else would. -The only part on the lid I'm even slightly worried about is the push button mechanism. It seems very sturdy, but getting opened dozens of times a day every day might be rough. I will update if it ever snaps. If I haven't updated, you can assume the latch is still holding firm. Any other complaints I have are cosmetic, so I can't really hold them against the product. It would be cool if there were more colors (the bottle I needed this for was orange). I like the classic nalgene look, these look a little over-designed for my tastes. All and all, when I wind up screwing up a new lid, I'm not sure which way I'll go. It'll probably depend on how this top is holding up. I definitely won't be upgrading unless the current tops on my nalgenes get damaged. A nalgene on amazon is something like $12, parting with $7 for a lid upgrade seems a little silly to me, but if I'm replacing the lid anyways, it's probably a toss up between the classic ones and these. If you need to replace your lid anyways, check them out.
