I suspect this may be a love/hate thing. According to some reviews, some people have had good results from it, others not.
Might be a good tool to use to pick out those remnants from your Xmas parties.
Never used one before so thought I'd give it a try!
Was £100, according to the website.
Prices are quite varied online, those most places seem to be selling for around £65+.
2% Quidco too.
