It's funny to see that you have maybe 3 people replying to all the comments related to vani-t. They must be distributors trying to get new clients on board.
I have been using Liquid Sun for around 5 years now and have never found anything to compare with it. I have always been exceptionally happy with the product. However, if I find a solution to better it then I will use it - have drawn a blank so far.
I have nothing to do with the distributor in the UK.
