good toothbrushes
These brushes are very good substitutes for OEM sonicare brushes.  They fit tighter on the toothbrush shaft, so they require more effort to remove and attach, but they don't wobble and are very sturdy.  The brush heads themselves work well and are not too stiff.  They are a bit stiffer than the OEM one I have (there are so many versions, it's hard to compare), but not so stiff that I would have concerns about using them.
