Query: Good Mirror, But Not for Straight Handle Bars

I tried these on my bike, my wife's bike, and our two kids. Good quality mirror for a great price. Our problem was that the mirror could not give us a good view behind us, due to our straight handle bars. I suppose these might work well on some, depending on the exact shape, size and configuration of the handle bars, but on all four of ours, no such luck. If you think you can handle a great mirror on the end of your handle bar, take a look at theMirrycle MTB Bar End Mountain Bicycle Mirror, and my review there.
