Although this product is really cheap, it doesn't taste great and if you are looking for something nice to drink spend the extra 30p on the standard tesco coke, which although isn't the best, is at least drinkable!

Advantages
The price- at 18p, you can't really buy anything much cheaper. I am a student and when things get tight I buy this to mix alcohol with. Considering you can buy around 10 bottles for the price of a 2l bottle of diet coke, it is really good value.

Disadvantages
The disadvantages really do outweigh the advantages.
It tastes pretty bad- I can't really describe the taste other than a pepsi with a really horrible after taste. It really isn't overly pleasant to drink after a while.
I've found it's very fizzy at first, which I don't think is a pleasant thing to drink and then it goes flat really quickly, which again isn't very nice. I have also found it seems to fizz up quite easily when you open the bottle and I have made a mess on a number of occasions with this stuff.
The packaging isn't overly appealing but the plastic bottle is of decent quality and I have reused them a number of times.

This product really should only be bought if you are are on a tight budget and can't afford anything else!
