Review on 😁 4 Pack Replacement Toothbrush Heads Compatible With Oral B Braun - Professional Electric Toothbrush Heads Refill for Oral-B 7000, Pro 1000, 9600, 500, 3000, 8000 by Luxme Johnson

I bought these as a cheaper alternative to regular brush heads b. Unfortunately, I found that I didn't like the groove on the brush head. I have sensitivities due to receding gums so I'm looking for softer bristles. I had pain brushing with this brush compared to a regular B brand brush. I like the flat heads and ended up buying another cheaper brand that closely mimics the B series brush. If you don't mind the groove, everything else about this brush head seemed excellent. It worked as expected and the bristles were intact.
