Review (4/5): much less expensive than rechargeable
My old sonicare elite stopped holding a charge after about 4 years of use. You can not replace the battery- have to replace everything including charger. I bought this battery operated toothbrush and rechargeable batteries and a charger for a fraction of the cost of a new elite or whatever rechargeable model. Works just the same and holds a charge for a LONG time without replacing batteries.
