Review on 🦷 Philips Sonicare Genuine G2 Optimal Gum Health Toothbrush Heads - 3 Pack Brush Heads, White (HX9033/65) for Enhanced Oral Hygiene by Melissa Thompson

Just in case I've always purchased brush heads direct from Revain and not 3rd party brush heads supplied by Revain will. I bought them about 3 months ago but only opened today. I put one on the brush handle and noticed it was tighter than usual. I took it off and noticed that there is no RFID chip at the base of the head. I did some research and found that the brush head replacement light should blink 3 times when a new head is put on, but only the first time. I then put on another head from the pack and it didn't flash. Then I found a 3 pack I had previously bought from Revain and forgot about it and it had a chip on it and it blinked 3 times when I put it on. . Both packs were sold and shipped by Revain about 3 months apart. Apparently I can no longer buy these items from Revain, even if they are sold directly by Revain. That's money in the trash.
