The Braun Cooltec CT2s is a great electric razor; far better than the series 5 I have been using on and off for a year now. In that year I have tried the new Wilkinson Sword Hydro Power
; and two other review razors in the Philips Sensotouch 2 and 3d's. I have now been using it on and off for a few months and have a chance to consider it after a longer use.
The first thing to note is the Cooltec really does work; shaving on dry skin with the Cooltec (draining the battery away) I get almost no razor burn on my neck that I do get when i use the Philips razors on dry skin. I have two shaving patterns; workdays I clean-shave and weekends I might miss a day. I also travel a Lot and find myself getting off long flights having not shaved since Mumbai or Bangkok. Like all electric razors the Braun needs me to shave everyday to neck stop hairs which grow along my skin rather than standing proud as they do on my face. Missing a day results in slightly longer hairs that none of electric shavers can do a great job with; and once they get too long the only way to remove without irritation is to wetshave.
In use the design lawnmower striping shaving style of the Braun shavers doesn't work as well as the Philips shavers; the rotary motion of the Philips results in a closer shave. All of them look clean shaven; but none of them give a clean feeling that lasts as as long as using a Fusion or Hydro wet shave does. They do give you a clean look and feel smooth for a few hours but soon I can feel stubble when i touch my face. That said neither of the braun shavers gives me razor burn; the Philips ones always do if i dont use a gel with them; so the rotary motion comes at the expense of your skin.
I found Cooltec CT2s a mixed bag; its as good at shaving as the 5 series but the Cooltec functions really works to protect your skin. I do think that Cooltec is a a bit like the American Space Pen; using gel already worked and it doesnt reduce the battery life. For me its the Sensotouch 3d that makes it into my bag; along with a pack of gel.
