Each bottle contains 150ml of product with a price tag of £4. I have seen a few reviews saying this is harsh and stripping, which I disagree with. It removes every last bit of nail polish from the nail and removes all the oils that prevent nail polish from adhering to the nail beds. It doesn't have the greatest of scents and can be overpowering, but you should use nail polish remover in a well ventilated room so this isn't an issue.
Overall, I think this is an effective nail polish remover! I would not say it is conditioning but it isn't harsh at the same time. I recommend you try it for yourself if you are struggling to find a worthwhile nail polish remover.
