Thanks for your quick reply, Steve, and helpful advice.
I've read elsewhere to be sure it is the Wago brand connector and not a knock off.
I know some may be inclined to try to save a small amount and end up with inferior product. While cost is always a consideration, I don't intend to try to save a few dollars (relatively speaking) overall on connectors considering how much I have invested and spent on everything else.
This Wago 3-conductor splice (or 5 way splice as suggested) does appeal to me more than the Posi-Tap connector for this application.
