It's a must if you are planning on hiding a cable away from the sign and if the plug isn't very close.
We were really pleased with our sign, made and delivered really quickly, very satisfied.
Bought this to go with the neon sign I bought for my son's Christmas present ..he was delighted with it thanks
I brought this extension lead for a sign I purchased from you as the plug being used is a distance away .It was packed in box with my sign and works great.
