Review on Wirefy 275 Heat Shrink Tubing: Efficient Cable Insulation for Professional Use by Jessie Ritchie

When I need heat shrink tubing, the first thing I do is go to Wirefy. In this case, I was let down by pre-cut heat shrink tubing of various sizes. Even if I use heat shrink tubing, I like to add a piece of heat shrink tubing for extra strain relief. It is necessary? Who knows, but I do. The problem I had with this pack of different sizes was that I started installing shrink butt connectors. Unfortunately, these precut pieces are exactly the same length as shrink butt connectors, defeating my ability to expand on the strain relief properties. Yes I could add a second piece of pipe but. Spring. Not me. I've only encountered this problem with butt connectors. When using these blanks for clamps: ring, spatula, ball. they work fine.
