FYI,

 

Pretty sure this is an older model that uses NiMH battery instead of the new model Pro 3 3000 which uses Li-Ion battery.

 

I just bought the Oral-B Pro 2 2500N for $92 off amazon which is exactly the same as the newer Pro 3 3000 with nothing more than the colour of a brush handle and an extra brush head differentiating these two.

 

Check out these two handy links for more info.
