EPen good for putting in "handbag" etc. No more leeks . I find the ecap flavours to be a bit bland , but because the pen is easy to assemble and use , and I don't use everyday, that negates poor flavour. I would recommend to anyone who wants a pen to use on the go for short periods of time. The price seems a bit excessive but there again that's always the case when restricted to one online site t o choose different strengths etc. The shops that stock them only have the one colour of pen and only the high strength caps.
