"wonderful but . . ."
05 February 2011
This is a great product and really works but I agree with other reviewers that it only works for 20 or so washes. As much as I wish I could afford to buy them more often, £6.99 or even the Buy Two offer is not economic if I have to replace them so frequently which, for the number of colour washes I do (four or five per week) is about once a month.
