Crap Gadgets
We wanted a monkey butler and bought one off eBay. Imagine our surprise when we found it was just an ordinary monkey with rabies. Worse: It had no butler training at all. Tell us about your duff technology purchases.
Thanks to Moonbadger for the suggestion

they contain an RF preamplifier circuit which acts in place of gain-boosting elements
that you see in a conventional aerial design, i.e. lots of slices of metal in a line providing a resonant path of the signal to the dipole (shape of a squashed staple). I've seen inside one of them and it's just a foil outline on cardboard with a small amp IC- unfortunately the front-end of the TV also has an RF amplifier IC so you're ramping up the distortion by amplifying something that's already been amplified. Which is why they are shite.
