I do not know the here often called RQ12 / 50 and would therefore like to describe my experience with the RQ 12/60.
First, I'm thrilled - the shaving is worlds better. But I also expect from a product that is new 3 years!
Price:
I bought the 60 RQ12 / 55 euros. Whether this is expensive each may judge yourself. But the cheapest Shaver 9000 Series is just under 160 Euro! And this quality I achieve now in any case with the Arcitec 1050 essay RQ12 / 60 in any case also. As such, I've saved over 100 Euro.
If I compare with the consumption of Gilette Fusion blades replacement of the head every two years is also much cheaper!
My Opinion:
The modified form does not bother me. Whether I aufklappe the three separate chamber and holding under the water or the skull diminish now and do clean under the tap is me frankly do not care. Sauber is both, and a time difference I have not found. The monthly cleaning requires a little more time but I prefer to dissect everything and clean it thoroughly. That was not the RQ10 / 50.
The shaving is definitely much better and I did not already in the afternoon are a gray shade.
So I give the product 5 stars and am happy with the upgrade of my shaver.
