With helmets you get what you pay for. Any helmet will offer you good protection as it will have to have passed EU and British standard. So in that terms it's fine. However with cheap flip helmets there is a chance of the flip coming up, though the rest of the helmet will still be offering protection if it does. The other issue with them is the amount of wind noise you get. I bought a flip helmet for £40 in a sale so I assume it is normally about £60 and the noise is ok but I tend to ride with ear plugs because of it now. To answer your part about glasses flip fronts will help you no end! I bought mine because it's easier to wear sun glasses with them, also it save a lot of time with paying at petrol stations and if you just stop for a moment, you don't have to take it off, so they are good. So if you just need a helmet then yes this is very good. Personally though, I think I would rather buy one that is better quality and will have better ventilation, protection and sound proofing.
