This shaker bottle is a sanity saver in our house - the DDs like chocolate milk and I hate mixing the chocolate powder as you can stir for ages and still get manky bits (the frintsels as DD2 used to call them when she was 4 - who knew there could be a word for it?!). This Poundland shaker (I think it's supposed to be for mixing protein drinks/diet drinks) is fab as it has a plastic mesh - just chuck the milk in, throw the powder or granules in, clip the lid FIRMLY on and shake! The bonus is it looks frothy in the glass too :)
So much though I love my Miele vacuum and Parlux hairdryer (previous MN recommendations!) this little gadget is just as covetable in my house
