There is no reason for them to bother getting UL certification, CSA approval or any kind of safety certification except marketing wankery. Battery operated devices like this don't require any safety certification.
Now, as to whether they'd be
smart to do some safety tests to attempt to be sure the thing's not going to burst into flames, that's another story!
I don't have any confidence at all in their abilities to properly test their own product given their complete lack of basic knowledge and understanding, willful ignorance or whatever their problem is, whether or not all this hokery-dokery that they're doing is intentional or not, given their previously released information (and lack thereof), claims and "test" protocols, etc...
Simply clueless!! (Or, perhaps, extremely brazen to try to fool people with such obvious quackery if they really
do understand that their product is an impossible fraud...)
