Hi, I've been a loyal customer for a couple of years now. I've tried many different TV liquids and there are only a small number I really like.
I'd like to try many more but to me its too expensive to just keep throwing stuff away especially when the shipping (and delivery time) to Australia is so expensive ..last shipment I believe I paid around $30 for shipping alone.
Anyway quite a few other vendors allow customers (registered ones obv) to leave comments and ratings on all their products. I think this would really improve your customer satisfaction and encourage customers to try new stuff as well as help them avoid wasting their time and money.
