There’s no other way to go other than ‘Take A Look’ for various reasons but the best one is if your mirror is on your head you can see a lot more than if it’s on the bike. Rotating your head allows you to see pretty much everything behind you. That’s damn near impossible with a bike mounted mirror.
And the good folks at ‘Take A Look’ will replace mirrors that are damaged (for whatever reason) for a couple of bucks if you send in the old mirror along with that $2.
