Query: What power?

Not much movement of the head and it takes more pressure than you might think,for it to work.It looks like a Braun,but doesn't work like one.The only thing going for it is the soft brush head,but the flexible neck makes it hard to use even with the power off.A manual toothbrush is easier to use. Coming from a Sonicare and OralB power brush junkie,it was a huge disappointment.
