Query: Do not buy HQ55(+); no longer made and the cheaper HQ56 work

I was looking for replacement shaver heads for my older Noreclo model 6613X electric shaver. On the shaver it says to only use HQ55+ replacement heads. This seller had the only HQ55+ heads on Amazon. Do not buy the HQ55 or HQ55+ from this or any other seller. Norelco no longer makes either. Instead, this seller will send you HQ56 replacement heads, which works just as well but can be purchased for about $4 less directly from Amazon (plus no shipping if you are an Amazon Prime customer). No where in the product description does the seller indicate this is actually an HQ56 rather than an HQ55, which is deceptive and will cost more for the same product. The HQ56 heads are fine. It is nice to have a nice close shave again, I only wish I did not feel as though I was taken advantage of by an unscrupulous advertiser.
