Overall::
Performance:
Came third for keeping our drink hot – it had dropped to 50C after two hours. It isn’t watertight, though, so needs to be kept upright at all times.
Ease of operation: 
Simply slide back a flap on the lid and take a swig. The handle makes the Thermos easier to pick up – especially if you’ve got small hands – because the upper body of the cup is fairly thick.
Buying: 
It’s hard to argue with the £3 pricetag – which even includes free delivery. The Thermocafe wasn’t brilliant at anything, but was good at most things.
Quality:
It felt surprisingly classy given the bargain-basement price. The brushed metal casing should be hardy and resist scratches.
Special features: 
Not a lot here – but what do you expect for three pounds? A plastic handle with indentations for your fingers is about your lot.
