FIREKI Tumbler (40 oz, Gloss Pink)

My actual score for this product is 3.5 but since half stars aren't possible I chose to grade on a curve. This product is well-constructed, durable and comes equipped with a leak-resistant lid that competitors often force customers to pay an additional amount to receive. That's why I graded the cup on a bit of a curve.As for performance, I compared this cup with an Rtic 30oz tumbler, an Ozark Trail 30oz tumbler and a generic 40oz powder-coated bottle I purchased from WalMart called a Quench Hydration. I am not a professional reviewer I just made a new year's resolution aimed at drinking more water which led me to purchasing multiple tumblers and bottles. I quickly found that drinking vessels without insulation not only failed to keep water cold enough to be palatable for long, but left rings all over my workspace on the job and furniture at home as well.For my purposes keeping items cold was most important so I never tested out the heat retention features. I filled each cup or bottle to the top with ice and kept track of how long each retained their ice before melting. I retained one uninsulated bottle as the control subject to get a gauge on when ice should melt and wanted to reference the rate at which the other cups/bottles let ice melt.As expected, the uninsulated bottle's ice had melted down to liquid within a couple of hours at room temperature. To my surprise, the $11 Quench Hydration 40oz powder-coated bottle held ice longest. I stopped counting after 72 hours. It was the most expensive item on my list at $11.00 and was by far the best performing. The Ozark Trail & Rtic Tumblers held ice for over 30 hours in a room temperature environment. The Magnum Solace 30oz tumbler came in last holding ice for around 20 hours at room temperature. My liquid stayed cold for a full 24 hours, but by 27 hours the Magnum was at room temperature. Meanwhile, both the Ozark Trail and Rtic tumblers kept liquid cold for around 34 hours.In practical use for someone who only treks from the office, to the gym and then home it's hard to go wrong any quality double-walled, vacuum insulated product. While the Magnum Solace doesn't quite have the staying power of the Ozark Trail or the Rtic tumblers, it is the cup I use most often because of the closing lid. I paid 10 bucks for the Magnum Solace on Amazon and found it a fair price.

**UPDATE** I bought this cup in January of 2016. Apparently, they had a bad batch of cups and the cover at the bottom of the cup came off after a week of use. I wrote to the manufacturer and they replaced my mug for free with a new one which I believe is a much better design. Excellent customer service! This company truly values their customers and now makes an outstanding product. This cup keeps my morning smoothie ice cold for a long time. I always drink it within an hour so I don't know exactly how long but it's plenty long enough. The lid is made from very durable plastic and has survived being dropped a few times. The gasket on the lit comes off for easy cleaning too. I wish I could give 6 stars.

So I had this product for about 6 months now. It’s overall an okay product, but it does have 3 major flaws:1. The plastic lid, though dishwasher safe, smells like dishwasher soup. There is no way to get the smell out of the lid, nor the straws. I wish I’d knew in advance.2. The unit itself is somewhat wobbly. It does stand on a surface flat, but it is not very stable at that. I can’t count the amount of times this thing fell over and spilled water on my floor3. The lid’s rubber seal moves around with use and becomes somewhat lose. The lid’s straw opening design is such, that you will spill water with sudden movement.

1. Beautifully made, durable tumbler/cup/mug/what-have you.2. Nice balance when full.3. Excellent thermal performance. Hot stuff stays hot, cold stuff stays cold. If Yeti's "better" I can't tell nor care.4. Minor ding: accompanying "sippy lids" have slide closures with small slots - which are hard to clean/gathers debris etc. even after dishwashing. This can lead to long term unsanitary results (.... without lotsa soaking beforehand, Oxyclean, what-not...) Solution: use replacement WalMart "Ozark Trail" sippy caps that don't have slide closure. (I have the OzarkTrail 10oz tumblers and their sippy caps [without closure] fit 100% A-OK! - and are available cheaply.) Perhaps Amazon has some alternatives; my bet is these share fitment with Yeti/RTic etc. caps & matching generics.These tumblers are a unique size (24oz) not offered by others and yet do not have larger bases or a huge "stepped" topso great for driving using today's larger-size beverage holder openings - great for a big iced tea + plenty of ice, lemonetc.Happy.

Nice product. Keeps hot liquids warm for hours. Gorgeous color too! I have been looking for this color in some of the more expensive competitors with no luck. I added a little personalized decal and made it all my own! I am so happy I found this!

Love my tumbler!! Dropped it on concrete and it survived with minimal damage.
