My personal favourite is Berry as it just smells very strongly of berries with just a hint of alcohol mixed in. I prefer to keep this one in my bag for when I'm out and about and I opt to keep Citrus on my vanity to help perk me up whilst doing my make up early in the morning. The only negative I have about these hand sanitisers and in particular Berry is that my fingers feel sticky after using it which does disappear after a few seconds when it's been rubbed in completely.
From a price point of view, these are well worth the money as they're only 50p for 50ml which works out to be better value for money per use. I've been using both every day for a little under a fortnight now and I can see that each one will easily last for two months or so. I've already stocked up and have have two more of each scent in back up so I won't be running out any time soon!
