Spray function, no messy hands, easy to carry around
Hard to spray when it reaches the last 25%
Ease of use
This is a unique product as it allows you to apply barrier cream without getting it on your hands. You pump it over a few areas and it naturally disperses itself over the skin. Great for maintaining hygiene and also increases the speed of a nappy change!
Because it's a liquid in a plastic pump spray it travels well, better than creams in tubes.
Only weakness is that when you get to the last 25% of the bottle (similar with pumped suncreams) you can't get it out easily if you don't have the bottle upright, which is uncommon when you are doing a nappy change.
