  • Familiarity:I've used it several times

I don't know how this product gets so many five stars. I've used this thermos numerous times and every time it's a disappointment. I purchased a couple others since and both are superior to this POS. Thermos will keep your drink/soup hot for maybe two hours (at most) and warm for a few. My other go to Thermos (by Klean Kanteen) will keep coffee hot for hours and warm all day long. Don't waste your money.

The problem I have with Klean Kanteen vacuum bottles is that they don't come with a cup. When the liquid inside is scalding hot, it's nice to pour it out into the cup to let it cool. (I usually do this while I'm getting my gear racked and my shoes on at the crag.) I wish I could find a lightweight vacuum bottle with a simple threaded stopper (because the ones that have a complex pouring mechanism eventually break) and a cup.

Works well

  • Familiarity:I've used it several times

I was intent upon fulfilling my superficial goal of having a hot cup of coffee at the top of the mountain. The Primus keeps the coffee tongue scalding hot for at least two hours. I haven't tested it beyond that time frame, well, because I drank it all. Ambient temperatures have ranged from 28 to 38 degrees. It's small enough to fit in a Camelback MULE. I haven't been able to break it yet, and it's sturdy enough for trail use. No leaks, easy to operate with either of the two lids that are supplied.

Works well

Worth the money

  • Familiarity:I've used it several times

I used it couple of times so far; I've been using it in temperatures around 12*C, and I can tell that it can make it through the day (~8h) still keeping the liquids.. well, not hot, but not just warm.. Definitely worth the money, so far the best thermos I ever had.

Not bad for dual-walled Stainless Steel

  • Familiarity:I've used it once or twice and have initial impressions

I filled up the 0.75L bottle 24+ hrs. ago with just-boiled water and a single teabag, closed it up and left it in the window sill. Outdoor Temp. Variation: 14C to 20C back down to 14C, no sun. Not extreme, nor significantly cold, temps. After a full day the tea had cooled from boiling to that perfect tea temperature where you can just begin taking sips without burning yourself (probably from 100C to ~45C). 0.75L was the perfect amount for 2 full mugs of tea.

Maybe not as insulated as a glass vacuum thermos, but definitely safer, hardier and downright cooler.

Haven't gotten a chance to use it on the trail, crag or riding (bike messenger) but I'm pretty confident it'll hold up to my abuse.

Bottom line: Get it.

So good.

  • Familiarity:I've put it through the wringer

Keeps coffee hot, and comes with two different lids. One you turn to pour, the other you click to pour. Both work nicely and keep coffee where it's supposed to be. The bottle seems to hold most of a '10 cup' pot, and I love that it doesn't have a handle so I can jam it into my pack.

Does it's job

  • Familiarity:I've used it once or twice and have initial impressions

5 hours later, still piping hot. Very satisfied user. plus, I feel like I could kill a small bear with it. I know this thing will stand up to a beating when I take it on the trail.

Primus Bottle

Keeps stuff hot. If you use the traditional lid it drips a bit when pouring the first cup or two but I mostly use it for tea so I go with the quick lid which is AWESOME.

Everyday Essential Now

  • Familiarity:I've used it several times

Originally I purchased the 25oz version of this bottle, but realized I might not need the added volume for hiking and got the 17oz version instead. I couldn't be happier. The bottle is the perfect size for myself and maybe to share with a little with a friend. I would recommend the 25oz for a couple or sharing with friends. Quality of this bottle seems top notch and the grippy powder coating on the exterior makes sure if never slips out of your hand. It does its job keeping whatever I need piping hot and I couldn't be happier. This item seems to always come along with me when adventuring outside in the winter now.

Awesome Thermos

  • Familiarity:I've used it once or twice and have initial impressions

5 hrs on the job on a freezing weather finally got a break and to my surprise when i opened my PRIMUS VACUUM BOTTLE steam is coming out my coffee was like freshly brewed I never expected how good this bottle was highly recommended.

pretty good, not perfect

  • Familiarity:I've used it several times

the top edge of the bottle is a little sharp. I like how the cap can be used as a cup. Definitely keeps beverages hot, maybe not quite as long as they advertise.

Is there any kind of coating on the inside...

Is there any kind of coating on the inside of the thermos? If so, what is it made of? Other makers advertise BPA-free, etc.

Any buddy have a problem with pouring? Every time I pour my liquid out it spills everywhere. I am pouring it out of where the arrows are, this is with the screw top not the push top. I broke that one before I even got to use it.

does this have two cups? One on top and on on bottom of the bottle? I am confused about the name and picture. Primus website has one named primus c&H vacuum bottle duo that looks like the one in the photo, but it's only .75L.

mo,This package comes with 2 form fitting cups you can attach to the thermos (one on top and the other on the bottom). A lot of sites picture the standard C&H Vacuum Bottle and mention it comes with a additional stopper (plastic drinking cup). Hope that answers your question.Mahalo, Sumo
