I have been using JAC Vapour for over a year and have been really impressed, in terms of quality of products (hardware) and range of e-liquids at good value too. In addition to this, JAC Vapour has a superb level of customer service as any potential issues get resolved quickly and friendly.
A most recent example would be when I had a query (submitted via the contact us page), I got a swift and pleasant response from Heather Corrigan who was very helpful and acknowledged my long term custom. In less than 24 hours my query had been answered and the e-liquid in question had been dispatched. Very pleased and would highly recommend.
