Review: After a lot of research these were determined to be the best for the job - We needed isolation switches for our campervan electrics and after a lot of research we found that these were the most highly regarded. They do cost a little more than the cheap replicas but are of much better quality and there is a reason that replicas are created of these in particular. Easy to install considering we are noobs but that is thanks to YouTube.
Review: Good item - Excellent item, perfect for my motorhome.
