These are both great tools to have for the DIYer. Just for the safety aspect. Don't even have to do electrical work. Just to be able to test outlets, or check if a wire is hot is worth the $20.

As always, test on a known energized source before checking anything that you think might be off.

Not sure why you're getting downvoted. It's literally the same price at my local Lowe's right now.
That's because it's also on sale at Lowe's. It's not their regular price. The Lowes's sale end May 6.

It's still than the lower price before April 1. This is a relisting of the deal, it was previously posted. SD does this at times.
