Review: Like it very much made my work more simple
Review: I've used several of these on various Arduino Uno driven devices, and I consider them to be an integral part of building a functional device - as opposed to a test-bed use of a Uno. These provide secure, stable wiring options. They are not perfect. Wiring routing requires planning, and installation is affected by the lay of the wires, so plan carefully...don't just start hooking wires anywhere. But if you apply reasonable engineering design effort into your work, these will vastly improve your final product reliability, ease of service and operational security. Five stars, no issues. Work perfectly for my uno-controlled Slowepoke Pickup Winder. (see photo)

I’m not a fan of using pins so this allows me to quickly get my projects up and running without any hassle. Plus it provides more ground connections than available with the pins.
