A lot of the mugs on the market require the base to be pre-heated. Although very straight, Listawood mugs have issues with base printing, a heavy base, but a thinner mug. Printing the bottom centimetre is a pain.
I found that Raja/ Wycombe Rhino mugs and Xpres mugs do not have this issue and probably have a better distribution of ceramic throughout the mug. They are heavier too giving a more solid feel to them. There's no perfect mug though. If your mugs have a taper, parts of the blanket will not reach the mug properly, tightening the blanket can help.
