Agree, Wago’s Lever Nuts especially are a game changer.

Those DIYers who reject the “licensed electrician and I need a permit” model could benefit most from them - they’re almost foolproof.

Instead they’re expensive, hard to find as Lowe’s/Home Depot don’t sell them, and not too many average people are familiar with them.

I won’t ever buy plain wire nuts again unless it’s to cap a single wire.
