I think Volti and eddie both have a point .
For my money if the customer wants to pay for it, MK for me purely for aesthetic-al reasons but it can be pricey. The only bugbear is you can buy ii most times cheaper down B
and Q and if the customer goes down there..... Secondly the terminal screws are not the best small and if used a few times can shrear secondly the Fuse in the fused spurs can
be a sod to release.
However if you are not as lucky as eddie and do not get ALL your work from recommendation . Then the cold ,hard facts are that you have to compete with others to get a job
and I do not like working for them, but reality bites and some customers want the cheapest price end of so they will not be getting MK
