For me, those vials are necessary because many Liquid manufacturers (including mine) do not use any vial of needle-shaped "filler" and the ego-CC (unlike its predecessor) with this then no longer be filled.
The vials are odorless and slightly milky - but the liquid including color are clearly visible. The dosing is convenient and accurate enough for the purpose owing to the legal soft material. Also important: the vials not siffen and so the filling is a neat thing.
However, what bothers me: it's quite a hassle again to close the Needlecaps clean. The silicone of the closure cap has only a tiny opening and is also unfortunately very soft. Thus, it is quite difficult to close the "filler" clean. In addition, the actual needle is a little sharp and so with me always remains the uncomfortable feeling when closing might be a little silicone into the socket and thus get into Liquid. Often such vials (as in my case) to mix different liquid starches are used. Here is a graduated scale would be very helpful.
All in all, decent bottle for the price.
