Good product...but
I purchased these in March. The only difference that I noticed between this product & the OEM brushes is that the head was slightly smaller. I have had no problem with the operation of these. The first brush was replaced after 6 weeks. The only minor nit pick is that occasionally the inside of my lip slides between the head & the shaft, no problem. I will by these again for $5 instead of buying the OEM brushes for $30.<br /><br />UPDATE. I have purchase 2 packages of theses (8 brushes). Out of the first package all 4 worked as described above. Out of the second package the first 2 were good, the second 2 only lasted about a week.<br /><br />I have now purchase 'Generic Oral B Compatible Brush Head Replacement 4/8/12/16 Count for Oral B/Braun Professional Care/Professional Care SmartSeries/TriZone/Advance Power/Pro Health/Triumph/3D Excel/Vitality Precision Clean/Vitality Dual Clean' by oGee. These have been great. they feel better than the above.
