Summary: I can only echo what two other reviewers have said on other review sites. Beware of this product. The very flimsy plastic head breaks after a few uses making the product worthless. Philips will not replace this head/comb under the so-called 2 year guarantee because the head is not the product it is an accessory! I will be avoiding all Philips products in future as their guarantees appear worthless they have no apparent pride in their products.
