Review (3/5): Both work well, together
Brush heads are a little small but, cordless unit fits my hand well, runs a solid 2 minutes (the recommended amount of time to spend brushing), can be restarted using button on front of unit. Great brand just a little pricey. The powered pik unit shoots little blasts of antibacterial mouthwash or water. It feels good to clean between teeth and around the gums. Both units came together, in the same box.
