I have received my sensor replacement as mine was faulty. This one is very different to the ones supplied with the BigBox but in a good way. It has a detachable sensor! So if the sensor dies again then the wiring can remain and only the sensor be replaced! Now I only have to thread this new one through (i'm thinking tape it to the old wire and pull) or possibly cut the end off the current sensor and replace it with both plug ends of the new one!
