- Nice for tempremental cartos
The extension is sealed. There is no hole in the center. All the air flow is from the side cuts. These are useful to keep the juice out of you batteries connection pin if you have one that weeps a tiny bit too much.
It wont stop flooding completely but it does add another layer of prevention and a slightly tighter draw. Not much tighter but enough to help some devices.
I only gave it 4 stars because it adds a tiny bit of length too which is pretty much unavoidable.
