PioneerVacuum Insulated Flask, BPA 18/10 Stainless Steel Leakproof Travel Mug, Sweat Free Double Walled Design, Green, 500ml / 0.5L

Nice bright colour, easy to find in my bag. Just a metal bottle, no glass inside. Works well to retain heat, especially if you fill it with boiling water then empty it before you put your drink in. Downside - too small the lid for use as a cup. I need to carry a cup for drinking out of!

I normally don't write reviews but I feel quite disappointed about this product. It seems to hold heat suitably well. But after 3 days of washing and leaving it out to air-dry, it still tastes and smells of plastic. This should not happen. The plastic inside the lid also looks slightly cheap. Otherwise, we like the design.

tried lots of flasks and none have lasted more than a few months either dont keep hot for long or break. tried rhis flask first time.filled with boiling water and 6 hrs later still hot wirh steam coming out when opened..description says unbreakable fso fingers crossed.looks like a very good flask..unscrew top cup to reveal a push button which when pressed allows you to pour the contents out....only 4 stars for now .will see how it performs over the long term.

I love this flask keep does what it say. Your hot stuff with stay hearted all day and your cold stuff will stay nice and cool.

Good flash - keeps liquid hotter longer than my previous one.Nice colour(s)Pour-though stopper works well

Excellent design and, more importantly, keeps my coffee hot! Nice and light to carry. Well constructed. Recommended if you want a small flask to carry on shorter walks, for example.

Bought this as a Birthday present, they said it kept coffee warm and was small enough to go in a backpack comfortably

Good product
