Okay I have been wearing a Giro Air Attack Shield for about 4 years now and it's the best helmet I've ever had however Jay recently bought a cheapie helmet that looks like a Giro knockoff and really liked it so I did the same thing
Here's the helmet, looks almost exactly like my Giro

F8&psc=1 Grand total $32.97 so it can't compare to a $200 Giro right? well yes it actually can...
The fit and finish isn't quite as good as the Giro, maybe 95% there and it's not uncomfortable on my large lizard head
Ratchet is a large round knob that's actually easier to adjust than the Giro AND on occasion while riding with the Giro I had to push it forward but never had to do that to the Basecamp
Front shield held onto the helmet by 3 magnets which appear to be much more powerful than the Giro but the magnets rattle if you move the shield around, this isn't an issue during the ride
Front shield is larger than the Giro's and the view is GLORIOUS! Maybe because its new and not scratched up yet but I was impressed, slight optical distortion around the nose area but you don't notice it while riding, thought it might touch my nose which would be annoying but it never did
Shields are about $18 compared to the Giro's $40, I even tried mounting the Basecamp shield on the Giro but the magnet polarity is reversed and they repel each other, bummer
Not bad for $33 bux
