I've been swindled.
I bought one of these, and I've been using it, according to the instructions, as a way to sterilise incoming post. But it doesn't work. I'm hoping that all the post that I disinfected with it, was uninfected anyway - it probably was.
I've asked for a refund. I'll also be complaining to eBay about this fake product.
It is actually a disco light. Can you imagine the kind of person that would sell a fake disinfectant light in the middle of a pandemic?
