Cirkul 40oz. Lilac Stainless Steel Tumbler with Handle, All-Day StrawSip™, Double-Wall Insulated

excelente

Love it

So I read the reviews regarding this product, but it works. I found out a few things when trying to use it. First. You cannot tip or till the Tumblr at all. It has to remain straight. You cannot put a lot of ice in it and it has to stay under the max full line in the inside. I get flavor for the caridge on the lower setting. I don't think that you have to suck any harder than drinking from a normal straw. I like that it stays colder longer. It takes a few times to adjust to using but I think it's worth it.

Its not a STANLEY but it serves the same purpose. I don't like drinking plain water and this is perfect. The lid doesn't let anything drip out if it rolls over. Size is great 40 oz so 2 reg water bottles. If you fill it 3 times you went through one cartridge. I don't like fake or overly processed flavors. so its nice getting just enough and being able to control the amount of flavoring i get. I'm happy with the cartridges for now. I haven't been disappointed yet. I've been drinking considerably more water because of this bottle. Its built really well, so not disappointed. Its hit or miss on the ice retention. you have you balance out ice to water. The bottle actually keeps stuff pretty cool. I'm definitely OK with that. it does fit in most if not all the cup holders i have had to deal with.

I’ve been using the Cirkul 40oz Ranger Stainless Steel Tumbler for a while now, and it’s made a huge difference in how much water I drink each day. The large size is perfect for staying hydrated without constantly refilling, and the insulation really works—I can leave it on my desk all day and my water stays cold and refreshing for hours. The color I chose looks great too, and the finish has held up well without scratches or fading. One thing I really appreciate about this tumbler is the flexibility of the Cirkul system. Being able to use flavor pods makes drinking water a lot more enjoyable and helps me hit my daily hydration goals. I did run into an issue with a few pods not working properly, but when I reached out to customer service, they were quick, friendly, and very helpful in resolving the problem. That kind of support makes me feel even more confident in the brand. The overall build quality is solid—the stainless steel feels durable, the lid fits securely without leaking, and it’s easy to clean. I’ve used plenty of tumblers in the past, but this one has become my go-to because of its size, design, and how well it keeps drinks cold. If you’re someone who struggles to drink enough water or just wants a stylish, reliable tumbler, this is definitely worth it. I’d recommend it to anyone looking for both function and style.
