Is it UL approved (expecting the answer no)? If not and you have a house fire, your insurance could be invalidated. Up to you to find the consulting engineer to prove it wasn’t this gadget that caused it. UL stands for “Underwriters’ Laboratories” - its principal jobs are (1) to enable you to identify safe stuff and (2) to enable the insurance company to avoid paying out if you use unsafe stuff.
Unless this thing is UL approved - and I don’t mean has a fake Chinese UL sticker - avoid.
