asobu Urban Insulated and Double Walled Stainless Steel Bottle 16 Ounce (Marble)

I have this in the green, and decided to come back to get the marble. This tumbler keeps warm for well over 18+. It feels great in hand and is very unobtrusive. I’m a person who delights in having my tea throughout the day, so this marvel is exceptional and I have tons of stainless steel tumblers. This is the one!

I have two of these and they are my favorite overnight water bottles. I wish they had larger sizes for daytime use.the only negative is that you have to be careful when screwing the lid back on. Both of them got stuck a couple of times. I had to have my son-in- law get the lids off for me. I clean them in the dishwasher and put them in the freezer for a few hours before bed.

I use it basically to keep cool water. It has great insulation and keep my water cool for more than 3 hours. You can throw it in your bag and it won't leak. Great value for money.

Bought this to blend my beverages amongst a marble desk. It worked, and it keeps things really hot or cold. Recommend.

Great bottle. Keeps warm or cold all day long. It’s perfect size. Good quality and cute design. A little pricey...

Having had two of these flasks for a little over eighteen months I have found them to be excellent at keeping liquids cool but the caps are slightly awkward to clean properly. Every week or so now, I like to remove the silicone seal from the cap and clean the seal and cap innards as I noticed one had started to blacken after a short while as the flask had been used for squash and bacteria was starting to show up under the seal and in the cap threads. The seal and cap are easily cleaned once separated but it's not the easiest thing in the world to remove the seal and it could be easily damaged if you're not very careful. To this end I thought it would be a good idea to replace the silicone seal so I emailed the American dustributors/manufacturers and asked about spare parts for these flasks either seals or a complete new cap. Amazingly in this day and age of recycle/upcycle/save the earth's resources etc.etc. they do not provide either caps or seals as spares so the only option would be a new flask meaning the scrapping of a perfectly serviceable one for the sake of a pound or two for a new seal or cap and seal. Very disappointing.
