"I really like these mugs" star star star star star_border I was a little worried that these might be heavy and chunky but actually they are very lightweight. They are no more chunky than my denby coffee mugs and they do keep the coffee hot for much longer. I don't think they would survive a collision with the tap or another mug but at the price it would not be too much of a disaster. The only downside is that they have to be hand washed, hence the four stars.
