These are handy to have however they only hold 20ml of let down and on numerous occasions they have overflowed and ruined my top. It's also a good idea to make sure that the silicone is sealed properly the entire way around as again this can cause leaks.
More discreet than a Hakka but probably still not suitable for use out and about.
