I like the bottle holder

I like the bottle holder, but the cap with the water spout was not made very well. I couldn't get any water out of the first one, and had to return the whole bottle with holder  for a replacement. The second one is not easy, but better than the first! Why can't you just sell the cap with the spout!

This holder does not take up much room even though it holds 4 toothbrushes. The toothbrushes drip a little water into the bottom and I have to wipe it out occasionally. That is not a problem. I like it better than my old stainless steel one which continually got stained and never looked clean enough.

I like the little compartments it provides & the shape of bottles. They are easy to get out and put back in however closing the cap back down is a little more difficult than I prefer. It doesn't snap closed so I'm left wondering of its really closed completely. I've got water on myself before Bc of this. I love the pink color. Great sizing as well.

I had some difficulty getting the holder to stay together but after that works well. I did have a problem getting the bag out of the holder after it was full. There is an inner rim that holds the bag in place and sometimes that comes up with the lid. It's made of PVC so is light weight and sturdy enough for recycling plastic bottles.

I love this soap holders, I don't like having bottles in the shower, and with this holder I keep my shower floor clean from bottle marks. :)

Good product, I don't have to refill several times a day as it holds enough for half of my day. Without the carrier you are looking at a pretty unattractive silver bottle which is why I gave it 4 starts. I wish you could loose the trap and keep the bottle in the carrier. I tend to loose caps, so thank you for putting a chain on it.

Okay, it does hold water bottles, so like thats half of it's job taken care of right there. Glad we've got that out of the way. Moving on, The way it clamps on your bike is one of those rotate and flip shut type screws, which I expected, doesn't make for easy on and off in a pinch, but keeps the holder on....unless you have a thin frame like I do, then you tend to get the side to side issue. I would suggest to protect your bike that you have some thin foam shims or pieces on hand to protect your frame since the grip part has "teeth" yeah, teeth as in "this will ruin your bike's paint" teeth....otherwise does the job.

A very good bottle holder for my bicycle. It is very easy to install and very good looking and trendy

I purchased this holder for my bike without realizing that you have to screw it into the frame. I did NOT want to damage my bike just to install a water bottle holder, so I came up with an alternate way to attach it. I used zip ties through the top and bottom holes. So far it's working and hasn't messed up the paint, but it does shift slightly to one side or the other when there is a bottle in it. I wish the design was changed so that you don't have to damage your bike to install it, but my workaround is working for now.

I wish the size was a little bigger because I have to refill this more often than some of my other bottles, but the product itself is holding up to lots of use. I like the carry handle and flip top. So far has been a good purchase for me!

This is mostly what I was looking for, specifically trying to get away from so much plastic, which tend to add a bad taste. This Kanteen type is meant to fit in the normal bike cage bottle holder, but I could tell that it was going to get scratched up pretty quick using the aluminum tube-type of bottle holder. So I switched out my bottle holder with a plastic type (looks more like a cup holder), which works better with this 18 oz. Kanteen bottle.

Lastly, the rubber cap I hope will lose it's smell. There's that characteristic rubber tire smell in the little valve and while it doesn't taint the taste of the water necessarily, you can smell it as you drink so it's kind of the same thing. If you remove the top and taste the water, the water is fine. So maybe, over a short period of time, the top (rubber valve), will become scent free.

I like the trees design.

It looks like I'll still need to wash it frequently and the cap will eventually have built up too many grooves for my comfort.  I still prefer push pull over hyperflow (cover sold seperately) and closure cap (less comfortable to drink from with my mouth and less flow control).  The curve helps with grip.  It rolls or lays flat being both very light weight and easy to carry, when empty.  No negative impact on taste.  You can put more than just water in here, I just don't.

As long as I don't fill it to bursting and jump up and down on it, or other kinds of major abuse over the year, it won't leak, lol.

Even with patterns, people still give it the side-eye and come up with imaginative ideas of what it is.  When they think it is hospital gear, when they think IV bag, I don't mind, but they think something else, I do.  Other people say the curvy shape makes them think of a mini person.  Needless to say, this is some unexpected entertainment of sorts.  For some reason it isn't obviously a water bottle to people, until I drink from it, lol.  The caps look obvious to me, but I guess that's just me.
The one with the loop for attaching it to things is bulkier, but sometimes I miss that feature.

Even though I keep buying new ones, there's really nothing really wrong with my old ones.  They're easier to store than than old milk bottles and taste better for emergency water storage.  I exchange back and forth if I'm being lazy on cleaning up my current primary bottle.  The gravity purifier is probably better for those purposes, though.  (more water and filter).
Honestly, I'd be cool if they sold these in some kind of bulk pack, like they do the wine preservers.

I know nalgenes are the still rage and finally BPA-free, but they don't really offer any advantages that I'm interested in.  The knock off Platypus's might look more commercial, but I prefer transparency for cleanliness, etc. and those don't have the same quality material and construction.

The good:  Adjustable size allows it to hold bottles of different types in a secure manner.  Otherwise, about as good as any other water bottle holder
The bad:  No complaints here
The ugly:

Overall:  A normal water bottle holder with a little extra something.  Useful if you forget your bottle and need to grab something along the way that isn't designed to fit a normal bottle holder securely.

Very light bottle holder. Ideal for for road bikes. It is by far my favorite bottle holder out there. Easy to mount and to use.

Very easy to attach to my bike (diamond back). It holds almost any bottle no problem. I doesn't rattle like some other bottle holders do. Very happy with my purchase.

It's only a water bottle holder, but it looks sleek and nice addition to my bike. Easy installation. (2 mins)  Bottle fits tight.

This is perfect for my counter. It is not too large and holds all my bottles.
