Adagio Teas toasTEA Double Wall Stainless Steel Insulated Travel Mug and Infuser, 17 oz, Charcoal

I recently started drinking herbal tea and I wanted to take it to work with me. This infuser is perfect! The lid locks, making it easier to put in my tote bag to carry into work. No worries of it leaking, I have never had it leak! My tea stays hot for at least 6 hours as well! I work for the hospital, and often times I do not get a break until mid afternoon...a hot cup of tea is perfect for unwinding! I am so happy with this purchase!!

I really love this infuser. It keeps my tea hot for a long time. The lid is really secure. The only downside I experience is that the tea leaves somehow get into my tea. It helps to remove the infuser before drinking.

If you're looking for a tea infuser for on the go, look no further! This travel mug is the best for loose leaf tea. It is easy to use and has a lock on the lid, so it doesn't accidentally open when turned upside-down to brew. The tea stays warm for HOURS. The only thing I don't like is that I need my bottle brush to clean it because I'm unable to fit my hand in it.

The true test of a loose leaf travel cup is the ability to diffuse the tea leaves into the hot water, hold the tea at a high temperature for extended time periods and do so with no leaks. The toasTEA travel cup does this extremely well. It also easily supports one-handed operation, which is a must in the car. This cup comes highly recommended.

My tea warm for a small amount of time. I haven't had it very long but, it no longer keeps my tea hot.A big waste of money.

Love love love this cup does not leak stay hot and cold for MANY HOURS

It's awesome at keeping heat, lasts for 12 hours. The only thing is that if you open it after closing and inverting the bottle. I clicked the opener and it exploded open with hot tea drops of death on me. So open it carefully and away from you to release the pressure from the steam.

Keeps drinks nice and hot!Easy to clean and seals tight to prevent spills.

The best out there ! Exactly what i need ! Keep the tea really hot

It is extremely good at retaining heat. I burned the skin off my top lip with my first sip. Very good quality but I am now afraid to use it!

This flask has a small tea container that screws into the lid. You then leave the flask upside down while the tea infuses. Sounds simple, and it is.The issues with this product all stem from the poor design of the lid.1) The lid opening button and the security catch are combined. At first glance this seems ok, but the problem is that only needs a small amount of upward pressure for the catch to slide up and the lid to pop open. It came open in my bag on my second day of using it, as I walked a short distance from my home. I had taken care to ensure the catch was in the locking position. As the flask was upside down, the result was a soaked bag, and a loss of confidence in the product.2) the lid has insufficient insulation. as a result, tea only stays hot for around 4 hours.3) the part of the lid that flips up is flimsy. This makes closing it difficult when when you're holding the flask with one hand, as it flexes to the side.I also own a Thermos Ultimate steel travel flask, a similar design (without infuser), but has a far superior locking mechanism and has never come open in my bag. It also has a much more robust lid and stays hot for 10 hours.In conclusion, if this issue can be addressed this would be a fantastic product. As it stands, for my use case I can't recommend it.
