Welcome Klondike.
I used to live in your area.... good memories.
Now, VIP.
VIP sell an old tech clearomiser with their 'photon kit'. They sell you 2 for £9.99. You can buy
FIVE for that money, no problem at all.
Everything about VIP is money first, customer second. I am not surprised they leak, they were outdated 2 years ago and nearly all of these products caused problems for users. It is highly unlikely you are filling them wrong, it's quite obvious to the user.
I need to go away and now establish if you use other, better, cheaper products... VIP claim you cannot use their product with other makes, I suspect this is more of their marketing nonsense.
Good old VIP... I bought some of their liquid in an emergency the other day. They say that their flavours are the #1 and you shouldn't even use other brands.... which is the most silly piece of scaremongering I have heard in years. They are part of ECITA and are effectively telling you not to trust other members of ECITA.... just silly.
