 Shopping hints of HAJDU
  • Size and shape. Before purchasing an appliance, measure the accessible area. In the case of smaller rooms consider the area necessary for opening the door. Knowing the right size can help you to limit the range of choices.
  • Calculate how much the appliance of your choice consumes, according to the technical data sheet. Supposing a ten-year lifetime for a household appliance, serious money can be saved by the monthly accounts (120 months). So, taking the long view, it pays off to buy a more energy-saving appliance with a relatively higher price than a cheaper one with greater consumption.
  • Do not buy products of uncertain origin with no papers.
  • Compare the parameters of different products belonging to the same category. HAJDU offers long-lasting, energy-saving products on an advantageous price.
