A couple of years ago there was someone in our wholesalers peddling those black egg shaped things.
They looked and felt awful, cheap thin plastic, held together with cable ties, bodge a bit of heatshrink round it to make it IP rated.
Looking at the pictures on here i've yet to see one neatly put together and easy to follow for the next person, they look like a mess of wires squidged together. To me they just look like a bodge it together and shove it under the floorboards soloution.
They're a damn site tougher than any heavy duty JB I've used in the last 26 years.
