Philips runs its own product-testing programme at producttester.philips.com. Anyone can register, browse the products currently up for testing (electric toothbrushes, shavers, kitchen appliances and more) and apply by answering three to six short questions per product.

If you are selected, the product is sent to you to use and review. Philips’ UK page says that after you have finished testing and left your review you may keep it for free – only in special cases, stated in the test description, does a product have to go back.

Places are limited and selection is based on your answers, so applying is no guarantee, but there is nothing to pay at any stage.
