Review on 50-Pack Lever Connectors Nuts 5 Conductor Combination Compact Wire Connectors Fast Connection Terminal 28-12 AWG Multi Type Compatible by Steven Barbon

None of the XHF lever wire connectors have UL or CSA/US listings, so using them for house wiring in the US (120v - 240v) is technically a violation of the NEC. The WAGO version does have UL certification for grounding and bonding applications so is OK to use. Best Buy should make this clear in their description of this product. UL and CSA approvals are intended to insure safety so using unlisted wire nuts could result in hazardous situations, such as fire or shock. XHF should get safety approvals before showing these in use for lamp fixtures and house wiring.
