Review (2/5): Not all it's hyped to be, expect more for the price
I purchased the Norelco 9170 for the following reasons:
1. Three rows of cutting blades to shave faster
2. 90 minutes of shave time per charge
3. A timer that shows how much time is actually remaining versus other models that just tell you the battery is getting low.
4. Easy to clean.
In reality, it does not shave faster than my old Norelco, nor does it shave closer than the old one. The 90 minutes of shave time? The first time I charged it up before the first use, it charged to 85 minutes. The second charge went to 80. I'm now on the third charge and it's down to 78 minutes. I also noticed that as the battery runs down under 20 minutes of shave time, 10 minutes mysteriously drop off so in reality you get less time than what the full charge shows.
It is, however, easy to clean and more quiet than my Quadra. That's the only advantage. I wish I hadn't wasted my money on this model and had purchased a less expensive model. The jet clean system just wastes space in my bathroom.
Overall, I'm rather disappointed at the product I got, especially for the price paid.
