Bests & Worsts Reviews from Amazon

I fell into the same trap as others. Oral-B makes two versions of a "Sonic" toothbrush. For those who are critical of the negative reviewers, let's look at some of the facts. At the Amazon website, the two toothbrushes are entitled (1) "Oral B Pulsonic Sonic Electric Rechargeable Power Toothbrush," and (2) "Oral-B S-320 Sonic Complete Toothbrush Power Electric Rechargeable." Both are vibration-style ("sonic") toothbrushes. Both use the term "Sonic" in the product's title. At the Amazon page for these replacement heads, the one-sentence product description is: "First Quality Generic Replacement Brush Heads For all Oral-B Sonic Brushes." Since I can't bold or emphasize the critical wording, I will repeat it: "ALL Oral-B SONIC toothbrushes." Nowhere on the page is it mentioned that the brushes will fit the "Sonic Complete," but not the "Pulsonic Sonic." To figure this out, you have to either be very aware of the Oral-B product line, or read all of the one-star reviews before buying. I usually do the latter whenever shopping at Amazon, but neglected to do so this time. So maybe that's my bad. But I still think the seller here, under the circumstances, should be up front pointing out that these replacement heads will not work on the "Pulsonic Sonic." To not do so after saying they fit "all" Oral-B sonic toothbrushes is deceptive. Other reviewers point out that the seller does not allow refunds, so I guess I'm out of luck. Returning them for credit is more trouble than it's worth. I also want to mention that I got these at Amazon for $1.29 per set of four. That comes out to 32 cents per replacement head. I bought four sets of four heads, and factoring in shipping ($4.87), it comes out to 63 cents per replacement head. That's a pretty good deal even if they don't last that long. If they're being offered at considerably more than that, you might want to wait until the price comes back down. Whatever you do, make sure you're aware of which Oral-B sonic toothbrush you have and do NOT buy these thinking they will fit an Oral-B Pulsonic Sonic.
