Question about Philips Ersatz-Scherköpfe

Caution: The 'Philips Shaver Series 5000' is also listed under 'Suitable model' in the specifications. THIS IS NOT CORRECT! This product is only for the 1000 and 3000! Incorrect information leads to a bad purchase and since the packaging is already open because I only realised it when I was using it, I can take the price off my hands and throw the blades away. Thanks for nothing!
