First and foremost, you're more than likely buying the original component that was in your appliance from day one. If your appliance has gone ten years without service, you should be able to expect another great run out of the genuine, original component.
Secondly, the appliance manufacturer has selected the component for its spare part option or for the appliance originally, therefore making it the best option for the design of the appliance. The appliance manufacturer has to minimize warranty repairs and promote a good reputation for their model of appliance, so it has to be a reliable component.
Third and the most important, the genuine original components aren't cheap inferior copies sold elsewhere - to pause for a second, we only offer quality replacements, any of our alternatives are supplied by genuine manufacturers of other components / brands or by going around the appliance brand - some places are here for larger profits or to beat everyone else's prices by getting in cheap elements or pumps. I'm here to be the guy in the middle with both great prices and the best components.
Brands like E.G.O, Askoll, Robertshaw, Invensys, NSK, SKF and ICAR are all leading brands in their area of expertise. The components I stock are through the best brands on the market. So you can trust the parts you buy, are the best and reliable.
I will make a separate category for genuine originals once more are stocked, so if you're specifically after the best genuine parts at the best prices, you have your own section to view.
