I have not used a wrist mirror but have used a helmet mounted mirror and a brake-hood mounted mirror (velcro strap, drop bars, not brifters).
Both mirrors vibrated too much for me to effectively use them and both needed very frequent re-adjustment. Those issues aside, the biggest problem with the helmet mirror (other than having to wear a helmet) was knocking it and it becoming detached. I believe that it left my company on the floor of the Saxon Mill pub near Warwick. Similarly, the biggest problem with the handlebar mirror was it interfering with the use of my rain cape.
I can't use a bar-end mirror on account of my bar-end shifters occupying the spot. I would like to have a mirror but have pretty much given up on finding one that will do the job and be practical.
