I have two very similar electric toothbrushes for sale by Oral-B. Both are sealed in box.
1) Oral-B Triumph Professional Care 9100 (same as 9400 version).
As seen here $160 at LD:

2) Oral-B SmartSeries 5000 with wireless SmartGuide (aka Professional Care 9900...SmartSeries 5000 is the new name)

The actual brush between the two models are exactly the same with same performance and specifications. The only difference is the SmartSeries 5000 has a wireless timer.
