Review on Oral B Electric Toothbrush Replacement Brush Heads - 4 Pack Cross Action Toothbrush Head Replacements Compatible with Braun/Pro 9600/6000/7000 and More by Lisa Dvorak

When I saw the price, I couldn't do without these brushes. When they arrived I couldn't believe how good they looked and felt for $7.99. When I used them I thought they really made you feel like I was getting a deep clean, but then as I continued to clean the head kept slipping up. You have to be careful when cleaning, otherwise it will slip off immediately. Unlike other interchangeable brush heads, the b electric toothbrush does not have a lock. Very annoying when you have to adjust the nozzle 3 times in 2 minutes. Very disappointed because I usually like interchangeable heads.
