They work as anticipated

When heated with a heat gun (or something else with similar temperatures), they shrink tightly, exactly what I was expecting. I wish white and clear tubing were included in addition to the blue, yellow, red, and green, but that's a small complaint. They work, which is what I mostly care about.

Marine grade as advertised.

Excellent product. Product worked as described and sealed an underwater connection. The length was a little shorter than expected, but that was my error in not verifying before I bought. Be sure to use this along with the Haisstronica marine butt connectors. After joing the wires with the butt connectors and sealing with the heat gun, you can close up with the heatshrink. Decent flexibility and overall great value for money.
