To answer one of the original questions/ criticisms though:
Castle dont just make and sell the MMM, they do a whole load of different items, and can only set their machines up to do one at a time, in large batches/ production runs. This means that if they have no MMMs on the shelf to send out as replacement items, you may have to wait a while until they can get some more made and sent out. Same kinda thing applies to repairs- if all the engineers are getting something else finished (to a dead line), repairs may have to wait until there is free time in the scedule.
As it is, I've never had any issues with their products so I havent had to test their CS- bullet proof MMM V1s are a rare thing...
