REDUCE 24 oz Stainless Steel Tumbler with Handle - Dual-Wall Vacuum Insulated Travel Mug, Sweat-Proof Lid & Reusable Straw - Keeps Drinks Cold for 24 Hrs, Fits Cupholders, Dishwasher Safe - Sea Glass

I have been using Reduce Cold1 Tumblers for 10 years now. I also use the Reduce Cold1 Stainless Insulated Lid which results in outstanding ice retention. It's much better with the Insulated Lid than it is with the Standard Lid. The anticipated ice retention times are accurately displayed on the lid packaging. My experience is I take 2 50oz tumblers with Insulated Lids to work at 6 in the morning, working outside, with them in the truck with windows rolled up, they keep everything cold all day, and even have enough ice to refill from an non-insulated container and have cold liquids for over 12 hours. Do not expect the same retention from smaller sizes (as noted on the packaging). My 40oz with the same lid pushes 12 hours ice retention, but nowhere near the 50oz. The ice retention with the original lid is not as efficient, as is to be expected. I'm not as happy with the Powder Coated Tumblers as I am the Gloss Painted ones. The first one I ordered with powder coat arrived with chips around the rim. It's further been my experience that the Gloss Painted finishes are far superior and durable to the Powder Coated finishes. Granted, they not be "in style" or anything like that, but the functionality is far superior to the Powder Coated finishes. I have yet to experience any chipping (or scratching) on the tumblers 40 and 50 oz tumblers with the Gloss Finish. Powder Coat??? As previously stated, some Powder Coated Tumblers arrive chipped out of the box. Please keep that in mind if you decide to purchase Powder Coat. As one reviewer mentioned, I wasn't as happy with the length of the straws in the 50oz mug, and purchased 15 inch 6mm inner diameter flexible silicone straws (that came with cleaning brushes) I've used very satisfactorily. I'm obviously a very satisfied Reduce Cold1 Repeat Customer. I do highly recommend the Stainless and Gloss Finish Tumblers, and while I've had the same Ice / Cold retention from the Powder Coated ones, I cannot highly recommend them as well, due to the inherent characteristics of the Powder Coat to display wear (chip, scratch) when subjected to equal use. I hope this helps you with your decisions. (Admittedly, I did add some tweaks, but that does not detract from the quality I've experienced with Reduce Cold1 Tumblers.)I've come back to answer some concerns I've seen about Ice Retention in other sizes. I've owned Reduce Cold 1 Tumblers for over 10 years, back when the only options were to order from the Reduce Cold 1 Web Site, or Brick And Mortar stores, if you were lucky enough to find any that carried them, long before they became available on Amazon. I own 30 oz, 32 oz, 34 oz, 40 oz, and 50 oz tumblers. It has been my personal experience that the smaller the tumbler, the less ice retention you will experience, even using the Stainless Insulated Lids, which I use religiously when I'm going to be outside or traveling. If you are interested in sizes smaller than 40 oz, be advised, the 40 and 50 oz sizes have superior ice retention. Look up the Reduce Cold 1 Stainless Insulated Lid, and compare what the manufacturer advises you can expect in ice retention. They do practice "Truth In Advertising." The smaller the tumbler? The less time you'll experience when it comes to ice retention. (In fact, my Sam's Club House Brand 32 oz tumbler has roughly the same ice retention as my 32 oz Reduce 1, but since the 50 oz is my Go-To and 40 oz my fall-back, I'm extremely happy with the ice retention using those sizes.) If ice retention is your primary objective in your decision, please keep in mind the smaller the tumbler, the less ice retention you can expect before you purchase. Reduce Cold 1 is still my primary tumbler, regardless of size. Because of the reliability I've experienced, the only reason to purchase a new tumbler now is because they have a new color that gets my (or family member's) attention...Not for any other reason. One last suggestion, if you are experiencing problems with the seals after years of use? After all, the seals do not last forever, and shouldn't be expected to either. I recommend Reduce Cold 1 Seals instead of wasting time trying others searching for a fit (the voice of experience from searching for best fit before I found Reduce Cold1 Seals, when available).

This is my second thermos. When I realized I needed to drink more water I decided to get this same thermos. This way I have my water all day and use my other one for my smoothies, teas, coffee, etc. They are made very well, with easy cap removal, I love the straw, the rubber rim goes on and off easily to clean, if I take a nap, even my smooties hold up nicely.

I love this cup. It holds enough that I'm not looking for more tea all the time. It keeps my drink cold. Love the lid because I can not use a straw and I can place lid where I want it.

Received cup with broken straw. Just wanted straw replaced. Hard to get Amazon to understand you just wanted a straw. I contacted the company and they happily sent me a new straw.

This is my favorite brand of tumblers and this one is great. Not too big or small and the handle is great.

I love these tumblers. I have 2 now. There’s great color assortment. They don’t leak. There’s no plastic touching the drink inside (maybe the straw. I don’t use the straw). The cup doesn’t affect the taste of water. They fit right into the car’s cup holder. Easy to hold and lift. My one complaint is at first the pull-open drinking spot is difficult to open. A very hard for someone weak out recovering from surgery open it. After a while, it opens no problem. The lid can be difficult to clean because of all the small parts in the cap where hard water sticks and leaves deposits and where germs build up. I find soaking it in vinegar solves that problem. I wouldn’t let those minor problems deter me from purchasing these. No cup is perfect!

This is our second time ordering this cup. My husband loves that for the size he can have water for the whole day when going to work. It also fits in the car cup holder which is a total plus. Lastly, you have the option to use it with or without the straw which makes us all happy!

I love this bottle! It’s incredibly durable, resistant to drops and completely leak-proof. It comes with a straw for easy sipping, but you can also drink straight from the cup. A fantastic way to stay hydrated.
