All or nothing

With waterproofing, it's really an "all or nothing" scenario. It's dry or it's wet. They worked for me. The only caution is that that the connection wire must be clipped a bit short my comfort so I also used the shrink tube as a precaution.

Waterproof Butt Connectors byu Ancor Mar

I have used other brands, and found that they did not seal as advertised. These Ancor connectors work very well - and seal evenly every time. They also don't seem to require as much heat as some others.

We use this in Automatic carwashes. It survives in freezing, mucky, wet, abusive conditions. Even at nearly a buck each, they are worth it!

Negative Reviews:

Not water-tight

These things do not shrink down to fit snugly even when a lot of heat is applied, thus are not water-tight and not weather resistant. The regular heat-shrink tubing works much better in my opinion, and it's quite a bit cheaper.
