Don't Last Like OEM, BUT Less than 1/3 the Cost
These aren't the same quality as the Oral B ones ($5.50 ea.) but at a cost of about $1.66 each, they're a pretty good alternative.  I had gotten about 3 months use on the Oral B heads.  I'm only getting about a month on these Oliver James ones before the moving parts get so loose that they either pinch my lips, or the vibration and noise gets to be too much.<br />  So, if I use 3 in 3 months ($1.66 x 3), my costs is $4.98.  A little cheaper than the OEM of $5.50.  All in all, the end result is almost a wash.
