I ordered an Stanley Aladdin Classic l ltr from here here yesterday to replace the Sigg which has been sent back. Arrived this morning!! I can't fault the Thermos except they are slightly heavy (should be tough and robust though). I'm now tempted to get the 1.9litre version for home emergency use and also the 0.47ltr version for outdoor use. The Stanleys appear to be very well made and very thermally efficient. Oh and the 1 ltr version does not leak either. The 0.47 version looks to have the same stopper and cup design as the larger models.
