I’m aware of the company behind them - They are a supplier of industrial toilet cleaning supplies/services who later branched out into putting vending machines in their lavvies that sold “Naughty Novelties” - Edible Knickers, knobbly condoms, sex toys, inflatable sheep and the like - including phero gel wipes, which were IIRC a pound a pop. And they did get results but I get the impression it was a very basic and pretty poor qulaity androstenone gel. Fine for lads in a club but not much good elsewhere.
I can only see this as a slightly more sophisticated/better promoted version of the same thing.
