I’m looking for a guide which tells me which mug Matt will allow me to press the 400/500 and 600ml water bottles and the 14oz travel mugs.

I have been on various websites but can’t find the answer.
Looking at various articles I think but not 100% sure travel mugs use the same Matt as the standard 10/11oz mugs and the water bottles use a 6oz heat Matt.

I don’t want to pay £40 for a Matt if it’s going to be the wrong one and I’m not one for sending things back if it was my fault.
