I'm basically scooter rolls in urban areas, with a demi-jet helmet. I was a little skeptical of this but I also had enough of nauseating exhaust fumes. So I tried the cheaper version 5, which I found very well on the spot because without comparison. But as it turned out lights and behind very old cars, I found unpleasant odors. So I offered the Respro and there, indeed, it was REVELATION! More smell of happiness! I wonder now why I did not make this purchase early! And I still have not met the syndrome gout in his face that scared me a little in the light of the evidence. By cons, take the helping hand to put it correctly. The adjustment again after putting my helmet (if poorly made you feel very fast ... ha!). I just advise to train ... For my part, I am careful to mount it to the top of the nose, in the fold between the eyes, but no need to bend the nose clip. It is less tolerant and more striking to wear its cheaper competitor, but much better filter (cartridges are interchangeable if you ever want to mix the products). So, sports breathing is certainly less easy. In scoote I have not seen any difference in terms of difficulty in breathing, by cons is more effective filtering and therefore in my opinion. By cons to reception, I let in air for 24 hours evaporation residue production of products that smell when opening the package. Worth every penny, but that it should be tested to understand! Certainly it leaves a trail around the face arriving but it fades quickly. M size is fine for standard faces (see box size motorcycle) and better tighten the perimeter of the nose than to have too large a thing ... The nose clip is also reflected in the interior of the helmet light ... I have pasted a matte black tape, as I colored in black the huge gray logo ... In conclusion, I highly recommend. It does not worth to hesitate so it's effective ... It always makes me a shock when I arrived and I remove the mask ... The city has a smell!
