As good as the OEM - but easier on the wallet! [SEP] After making the purchase of the Oral B (recommended by my dental hygienist), I wanted to try a couple of different brush heads - but balked at the cost for the OEM versions. I decided to try this set of Replacement Brush Heads and am so happy I did! The quality of these heads is great (look/feel like original), they fit firmly on the Oral B (no jiggling) and are a fraction of the cost for OEM heads. Win. Win. Win. I have been using the replacement heads for a couple weeks now (alternating between the Sensitive Clean and Cross Action) - and they are holding up as well as the original supplied head has. I will definitely purchase another set of these Replacement Brush Heads when the time comes. **** Highly recommended!
