I had a Third Eye and loved it. Seemed to have lost it during my long layoff from biking. I finally went to the LBS today to get my bike after a tune up and asked about a new Third Eye for my current helmet (an old Vetta.) Well, he only had the Third Eye that glues on and I wanted the kind that screws on since I may upgrade my helmet soon and wouldn't be able to use it on my new helmet because of the glue.

I notice that at least two shops online do have it. Nashbar at a very attractive price. But I opted to get a mirror on the end of my handlebars and see how I like it. I may like it fine. If not, I'll go back to the Third Eye.

I can tell you that, in my opinion, The Third Eye was wonderful. Yes, it takes some getting used to. But in a few days you're lost without it and it's great to have it. But I guess it's all a matter of opinion and what works for the individual.
