Looks well built. Elegant and low-profile solution to connect electrical wires without the need for soldering and heat shrink. Works with cable outers between approximately 7 and 3 mm. Seals well, but doesn't provide much in the sense of strain relief. I would not recommend using this when there is a risk of the wires being pulled loose. I will use them for auxiliary LED lights on my lawn tractor. I would choose a proper junction box for higher voltages or currents.
Fast delivery, good product received perfectly packaged. I am very satisfied. The seller is highly recommended. Thank you!
