Title: Pretty much useless
Review: I've used the other Pico products with the built in solder and adhesive heat shrink and they work great (see my other reviews), but these butt connectors are pretty much useless in my opinion. The solder width is far too narrow for the wires both the wires (inserted at each end) to be covered, but even worse, the heat shrink insulator turns soft before the solder melts and and the whole assembly then falls apart under gravity.
Is the review positive or negative?
