A PSA about Sonicares

[elfs]

If you own a Sonicare and are familiar with the compact head, don't buy the full-size head by accident. I did that recently and was really unhappy with the result. The magnets that drive the full-size heads are the same size as the compacts, but they have more mass to move and the overall effect is that the Sonicare just doesn't do the job nearly as well. I finally went and bought a pack of the compacts and the difference is quite noticeable. They really do a significantly more powerful job.
