I was looking for a hybrid between a Sigg water bottle and a Camelbak. Like the straw mechanism on the Camelbak, but liked all the aspect of the Sigg metal ones--except I don't care for non-attached caps or sports tops. This was a great compromise.

I only plan to use this for water, but I should note that the tag says not hot beverages or dairy products. Would not recommend this for coffee, then, even iced.

It really does seem to keep the cold water colder and there is no metallic taste.

I think the clip on the top looks pretty non-durable, and it might rust in the dishwasher. Everything else feels tip-top solid. 5 stars

This bottle is perfect!
It is really dishwasher safe...I gave up on my Sigg bottles because I can't stand to wash things by hand.
It fits in my car cup holder.
You don't have to touch the nozzle to flip the straw up...which is really nice if you are out in the woods with dirty hands.
Plus the designs are really cute. 5 stars

I wanted a bottle with a simple slim shape that could fit as easily in a backpack side pocket, work messenger bag, bike messenger bag, or clip to a belt or bag loop. I didn't want a weird curve like the Klean Kanteens, or some weirdo laminate that has to be treated baby-soft gentle.

I really didn't want a sip-top like a cheap plastic bike bottle either where you have to suck down water (seems like it'd be hard in a stainless steel vessel and it's hard to keep those tops from getting odors).

The sippy-straw top is fantastic. There's a sealed-hole at the top so you can sip your water without that weird vacuum effect you usually have with strawish tops. It's also really sturdy and already has taken a bit of a beating.

The most awesome part about the top is that the belt clip flips the straw up so if your hands are dirty, you never have to actually touch your drinking straw. Great if you're out in the wilderness or been spending a lot of time holding on subway poles.

The bottle isn't insulated so if your drink is cold, your hands freeze and your drink gets warm fast. I had it filled with ice and water in my office, and within the hour it all melted (get a coaster). On my bike, it was tepid by the time I got home.

The paint is already chipping at the bottom and it's only been a few days, so I can't imagine the enamel being that durable in the long run. 4 stars

I did a lot of research before investing in my first stainless water bottle after learning about the harmful chemicals from plastic. They are all kind of expensive, but I'm very happy with the Nathan. I got one for myself and one for my 9 year old daughter, who is a very big water drinker. We both love them. 5 stars

I was looking for a BPA free water bottle with a leak proof straw that would hold a lot of water but also fit into the cupholder in my car. I also wanted something that was easy to fill and dishwasher safe (in other words, not a Sigg). I couldn't decide between the Nathan stainless steel flip straw and the Camelbak "better" bottle so I got one of each -- the Camelbak is already in the recycling bin because I hate that you have to bite down on the straw. I am ordering a couple more of the Nathan flip straw bottle's because it fulfills everything on my checklist plus the flip straw mechanism lets you push the straw up and down without touching it. My only wish is that they made it in a 1L. 5 stars
