Unfortunately, as it stands now I cannot depend on it to work under my "normal circumstances", one of which being used while bicycling (that is, without modification from me in the form of magnets or mods to the spring). Understand I'm not against making modifications, but I want the modification recommendations to come directly from Armytek so that I do not void the warranty.
I have had the Wizard Pro go out three times on two road rides, mounted horizontally so the majority of the jarring has been laterally, not vertically. As a point of comparison I've used the ZebraLight H600w under the same conditions, and also while mountain biking (more demanding conditions) without issue, so I did not believe my use was too extreme for the Wizard Pro.
Additionally, I have now also reproduced the light "going out on being jarred" using the AW 2900 mAh protected battery (this is the battery with the three bumps on the negative terminal, to facilitate them being used in serial). For me, three out of three batteries, although it may be argued this is another poor choice of battery for this application because that battery is only about as long as the EagleTac.
Batteries tested thus far by me personally that exhibit the problem of the light going out:
EagleTac 3100 (protected) - during normal use
AW IC 2900 (protected) - hand held intentional tapping
Panasonic unprotected (generously supplied by Armytek) - during normal use
Note I'm not throwing stones. Since the issues began, my posts are simply reporting my personal experiences but leaving out personal opinions wherever possible (or at least that is my goal). Hopefully the information comes across that way.
