Perfect Travel Bottles
Love these and the color looks great. I needed something smaller for travel that fits easily in cup holders and backpacks, and these are perfect. They keep drinks at temperature really well, don’t leak, and are surprisingly lightweight. Great bottles at a great price.

Great water bottle!
These thermoFlask bottles are good quality and keep liquids cold for over 24 hours with ice still cubed. The straw lids are the second best thing about these bottles. Super convenient and spill proof when closed. I have 3 sets of these and may get more for different uses.

Great Value - Drinks stay very cold!
LOVE LOVE LOVE these water bottles. Ice stays for 24 hrs or more and it holds a lot of water for a full day out and about. We keep one of room temp water for our pup and one cold one for us. Easy to clean, built in stray works well and the handle makes it easy to carry.

Reliable ThermoFlask
I purchased the 24oz and 40oz bottles. I have used ThermoFlask bottles during the past 10 years or so. It is reliable, durable brand that has never failed me and my family. 24oz bottle is kept in my car as it fits nicely in cup holder. I usually fill it full of ice and cold water, and it retains the cold temperature at least 24 hours especially in the winter. 40oz is for home and work, its easy to hold and drink. I will keep buying ThermoFlask bottles as it has proven to be durable and great at keeping my water cold.

Great thermos with a small flaw
This thermos really impressed me with how long it keeps drinks hot and cold. I’ve used it for both coffee and iced water, and it holds temperature for hours without any leaks. It feels sturdy, looks sleek, and is easy to clean thanks to the wide opening. The only minor downside is that it’s a little bulkier than I expected, so it doesn’t fit in every cup holder. Not a dealbreaker, but worth mentioning. Overall, it’s a high-quality thermos that does exactly what it promises, and I’d still recommend it to anyone who needs something dependable for everyday use.

One of the best 24oz bottles that I use.
As described by seller. Have multiple 24oz bottles from Thermoflask and they work great keeping my water cold while fishing during the summer and year round. I will keep them for years.

Almost Perfect for Me! I rate it 4.5 Stars.
Pro: I purchased this set to use for cold and hot beverages. Size is quite tall and doesn't fit in any of my tiny kitchen cupboards that I can reach so I keep it on my countertop next to the coffee pot. It has a stainless steel interior surrounded by a pleasant to hold rubber covering that is easy to grasp. and hold. I consider it a good build quality and attractive. Nice large opening for easy cleaning and pouring cold or hot apple cider, coffee, tea and water. I drink a lot of beverages and they stay hot or cold for hours. I never use ice, but the opening is large enough to accommodate them easily if you like it. The outer rubber coating is NOT heat proof as I discovered when I set it on my electric stove metal cover. It still works well (after I peeled off the melted bottom part) because there is another layer of hard plastic that insulates the stainless steel interior from the softer rubber coating. I mention it only because it isn't something a super senior great grandmother (me) and/or your children might understand without instruction. Other than that, it's almost indestructible. That's the good part. Con: I don't like the lid. I find the handle annoying and awkward to turn on/off the larger cap. I like the small pour spout because the more often you have to open the thermos, the faster you lose the heat capability, especially coffee. For those of you that also dislike the handle, I have a solution! I used an old, old pair of pliers with a wire cutter capability that easily cut through the plastic close to where the metal hinge reinforces it. Do not attempt to cut through the hinge itself because it is necessary! Happily, I no longer have difficulty and that's why I gave it a higher rating than 4 stars. I rounded it up to 5 because not everyone is an old lady. HA!
