Very good service.
I expressed my urgency all within reason and they did everything to get it out the same day! Their parcel arrived earlier then a package from the east coast of Australia and I live on the west.
So big props to efficiency and customer response!
Functional, easy-to-clip extensions. For one, I made a "super-extension" to the anchor building by replacing the screw caps on the original batches. I used the originals as equipment closures.
