Braun Series 3 Replacement Shaver Head 30B - Compatible with Braun Electric Razors SmartControl, TriControl 340s 330s 320s 310s 300s - Replacement Shaving Blades for Men's Grooming & Travel Shaving Kit

everything is perfectMy screen got a cut in it so it would scrape up my face when cutting so I needed to replace, this was the right model and gives the screen and replacement blade.If you have one of the right models, it just pops on and works. It's the best one the unit.Works greatInstalls like it should and works. I get almost a full years worth of shaves. There are cheaper products out there (cheap is the word), don't waste your money buy the real deal.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.Super easy to install and makes my old razor work like new.Update 7 October 2012---------------------Buyer beware - my most recent purchase of this replacement pack (June 2012) contained the "wide" blade cutter. This is the same type of blade as in the official replacement pack for the 8585 and it is completely ineffective. I even bought another replacement when I was traveling because it was taking too long to shave...same result. This picture shows the difference between the two types of blades: http://www.amazon.com/gp/customer-media/permalink/mo4AIXSC44WNNE/B001VH6F9GTo get my razor to work better I had to go to the store and look at the cutters myself to find the thin blade cutter. I found it on a 31s replacement pack. Note that the 31s foil does not fit the 8585 so I had to use the foil I already had, which is fine since it was only a few months old.I don't know why Braun is messing with success but the wide blade cutter works horribly...other reviews note this as well. If the entire product line moves to the wide cutter I don't know what I'll do...switch razors probably. I really don't want to - I love the cleaning unit. I've got at least a year to figure it out, though, since I just bought a new cutter.Update 7 January 2012---------------------I've purchased another one of these and it works as well the one I reviewed over a year ago. I noticed that it started taking longer and longer to shave - at least twice as long as it took with new blades. I'm happy to report that time I spend shaving is again much less and still no whisker pulling. I still recommend this foil and cutter.Original review---------------About 8 months ago I purchased this replacement cutter for my Braun 8585: The quality of the product was very good.It is important to buy an original Braun product to avoid disappointment. I also appreciated the prompt delivery.This item was to replace the existing product.Fit for purposeNo problems fitting the new head. It works well and has given his old razor a new lease of life.Excellent itemThe Braun razor provides excellent service over the years with good regular maintenance. The replacement cuter and foil has restored the unit to new condition
