Review Tubing Ratios and Benefits

What happens here

After successful application, the narrator elaborates on the importance of the shrink ratio, noting that many common heat shrinks are 3-to-1, while he specifically sought out a 4-to-1 ratio (and even looked for a 5-to-1). He points out that the applied tubing, especially with the adhesive, makes the connection waterproof, preventing moisture ingress. This reinforced connection is now stronger and will only bend at the cable itself, not at the connector, thus prolonging the cable's life.

Goal: The narrator discusses different heat shrink ratios (3:1, 4:1, 5:1) and highlights the waterproof and reinforcing benefits of the applied tubing.
