Braun Series 3 Old Generation Electric Shaver Replacement Head - 30B - Compatible with Electric Razors SmartControl, TriControl, 340, 330, 320, 310, 300

Update how many years later....it is unbelievable as to how long this razor has lasted. I truly am surprised as besides foils and cutters....cleaning solution cartridges are the only other maintenance item. I looked at a new Braun razor but my battery still holds an excellent charge and besides minor wear and tear....it works like new with this new foil/cutter.First I will point out that I bought this because of other reviews and that it was confirmed to replace my head and cutter block on my 360 Complete Activator. With that, the standard replacement is the 51S which I did not purchase, but rather the 30B instead. There are two noticeable differences: first is the color of the plastic components. They are black as compared to the original which is silver--- makes zero difference of course. The second is the tooth shaped cutter in between the foils-- that is a big difference. The one major complaint is that the original cutting system would grab and yank out facial hair which hurts. It seemed to be related to that tooth shaped cutter, but either way I was ready at this point to buy a Panasonic. It was mentioned that this assembly does not grab hairs.... that I can attest to as I shaved as I always did and it did not grab once. I have a goatee and I usually shave my fave first before trimming it. Definite improvement and of course the 30B cutter is about $15 less than the 51S which is nice as well.The reason for the 4-stars and not 5-stars is that I am still not 100% pleased with the way it cuts overall. I have used Norelco rotary razors and after switching to the Braun, I swore I would never go back as it was a huge improvement. The problem is that there ends up being particular hairs that it will not cut without going at a handful different attempts and angles. With that said, I still give the razor setup a thumbs up. Other than that it brought the razor back to life and no more pulled hairs.Also to dispel any myths--- it fits. I popped off my original parts and installed this without any issues. 5-seconds is all it takes to change the cutter and foil. The attachment post and everything were exactly the same and this part is made in Germany. And to reiterate, the only perceptible difference that you will see is the center saw tooth part and the color of the plastic--- otherwise it looks the same. If the rest of my razor is still functional in a year--- then I'll buy another one of the 30B's to bring it back to life otherwise, I may try a Panasonic to see how I like it.Feb 2016: Just bought my third one and now that I look back, I do need to replace it more often. The last one lasted 2-years and was still going, just not as sharp as it could be. Once again, the price was right and I am happy with the results.
