1, No, 912 and 916 are built-in rechargeable batteries, are charged by the charger. The difference is that 916 has more than 912 a low voltage prompt light, 916 when the built-in battery voltage is too low, its prompt light will light, remind you to charge in time so as not to delay your use. This function is very practical, because the Philips charging shaver of this grade has no dual-use function, and there is no prompt light to remind you in advance of shaving half of the beard when the shaver is out of power.
2, don't be superstitious about blades, I think when these two razor heads should be the same, are HQ56, even if now with different models of the head will not have any significant improvement. Grade limit ~ The difference is not big, maybe some people feel very big. All I can say about that is that it may just be individual differences, and what you think is good is better for you.
3, why is the dry battery really bad? I feel incredible. The advantage of the dry battery is easy to use, the battery is out of power to change the battery on the line does not have to spend 8 hours to charge, and the dry battery razor generally has 90 minutes of use time, not like the charging razor generally half an hour or so. It is just that the dry battery is not too environmentally friendly, and the intermittent use of the battery can not be changed several times a year.
4, the elastic veneer system personal feel is still very necessary, it can adjust the Angle of the cutter head according to your jawline, which is very practical can significantly reduce the number of back scratching. Faster and less skin irritation5, Pentium PS3206 has a fatal shortcoming, that is, it can not be washed. Shavers that cannot be washed are not well sealed, and stubble will enter the machine in large quantities. It is easy to breed bacteria and even mites, which may cause folliculitis. So it's best not to buy shavers that can't be washed 6, Panasonic and Braun are completely two different types of shavers compared with Philips, the first two are reciprocating, Philips is rotary. The advantage of reciprocating is that the motor speed is very high, the knife net is extremely thin, and the blade swings from side to side to cut the beard so there is no tug under normal conditions. It is very suitable for thick beard to use, the disadvantage is that the noise is large, the vibration is relatively large, which is caused by the motor and the head swing, and there is a disadvantage. The disadvantages of the rotary type are basically the opposite of reciprocating - the Panasonic ES-LV series is quite good, and the Braun 7 series is also very good. You're asking a very general question. Matsushita and Braun shaver has at least 20 years of history, can moisten live to today has not been wiped out by peers, which must have its own unique.
