## Description

SIGG - Insulated Water Bottle - Thermo Flask Hot & Cold One - with Tea Filter - Leakproof - BPA Free - 18/8 Stainless Steel - 0.5L : desertcart.co.uk: Home & Kitchen

Review: A practical flask that does not leak! - This is a very well designed flask that has a nice matt finish. The best features are: 1. The size - this fits easily into my car's cup holders (most flasks didn't). 2. The quick release/lock - the flask can be locked and opened easily with one hand and does not leak. I've purchased several flasks from other manufacturers that claimed to do this and all leaked. The flask keeps the drink hot/cold for the times described. It is a little difficult to clean well due to the size of the opening but this is still bigger than some other competitors. The surface fish will scratch and I dented my flask after dropping it but it did not cause a puncture to the steel. Overall the best flask of this size I've bought.
Review: AMAZING! 100% would recommend. - I bought a 'SIGG Unisex Outdoor Hot and Cold Brushed Water Bottle' this year and it is THE most amazing bottle I have ever had. The quality is amazing. It also comes with a removable tea "filter" (for lack of better word. It stops loose tea from coming out of the bottle and therefore, stops you from drinking bits of tea!) I would recommend it to everyone! And amazing as a gift too. If I make tea and pour just-boiled water into it straight from the kettle, I'm not able to drink it for hours! That to me is a great testament to how well-insulated it is. I just make tea in a water jug and after a couple of mins, I pour it into the flask. I haven't tried cold drinks with it but it is AMAZING for hot drinks. The size is also perfect. 0.5 litres last me half a day, and if I'm out longer than that, I make tea in it again (I carry tea with me everywhere!). I think if it was larger, the weight would stop me from carrying it with me, so for me, this size is perfect. HOWEVER.... The packaging isn't completely recyclable because the front of the cardboard box has that little plastic window/film that lets you see the product in the box. It's a sacrifice I'm willing to make, as the quality of the bottle & reusing it makes up for the packaging. I can have hot drinks poured into it if I go to coffee shops for example and never use unrecyclable coffee cups etc!

Bought these specifically to take fizzy drinks and keep them cool. Brilliant at what it does, keeps things cool perfectly. The two part top is more complicated than it needs to be, but it works. Very happy
