has anyone else wasted their money on this? my advice is if u care as much as i do about your children then leave well alone!!!!!! they do not care and are not interested in anything other than your money! do not let them i to your house , they are like double glazing salesmen !!!!! i feel totally ripped off and taken for a mug. its all done in front of your children so iff u say no u are made out to feel like a bad parent and are letting your children down! very very clever!!!
