Please write up a review after a few weeks. It's always good to learn whether this sort of device lives up to expectations.
It's also good to learn how one person's needs and wants differ from the next person. As noted earlier, everyone's situation is different.

Also... I'm also hesitant to try something new and expensive. It's not unusual to be surprised later at how happy I am with the device and no longer care about the cost.
.. but there are also the times where you look at the new gadget after a few weeks and wonder "who can I sell this to?". Thank goodness for friends nearby and online who share their impressions and opinions!

(btw, a friend gave me his old DiNotte taillight that is ridiculously bright. I'm not going to use it. If anyone is interested, pleas contact me)
