Not much to say really, other than the fact that this shaker hasn't leaked so far. There's a grille at the top which, when you give it a shake, mixes up products nicely (no powdery lumps like you get with a glass and a fork). There are convenient measuring marks on the side (although these only go up to 700ml despite the shaker being advertised as 750ml).
You have probably noticed that there's a more expensive alternative by Maximuscle. I strongly suspect from the images that the two products are identical (both made by the same third party manufacturer) except for colour and brand printed on the side. So personally I'd recommend you go for the one by Lucozade, purely because it's a bit cheaper.
