A review of the Filzer dZ4L bike computer

This may be a good bike computer for someone, but it certainly isn't one for me. My experiences with two units have been negative.

My first dZ4L lasted only a few weeks after I bought it; it failed to survive a relatively modest Toronto autumn rain. As far as I can see, this is intrinsic in the design of the computer; the transparent plastic top seems to be simply pressed very firmly on the main unit, not sealed. This is basically tailor made for capillary action around the edges, so once you've got enough water exposure the water starts being drawn up the sides and into the main display area where it mists up the screen and then gets into the electronics. Result: dead unit.

After a year of more or less reliable operation out of the rain, my second dZ4L is now frequently failing to register wheel motion, resulting in either much too low speed readings or a total glitch. This appears to be due to the plastic mount warping (and expanding in the summer heat; hotter weather makes it worse and cooler weather makes it more reliable) so that it no longer firmly holds the computer against the mount contacts. It can simply stop working on its own, plus even small bumps seem quite prone to jarring it just loose enough. Rapping or pressing the computer into the mount can temporarily make it register again, but it's far from reliable and rather frustrating. Trying to use a map case or anything that rests near the mount on the handlebars is troublesome, because it seems very easy for a velcro strap or whatnot to put just enough pressure on the computer or the mount to let things come lose; even a very light touch can be enough.

I find this really unfortunate. The dZ4L's four line display is by far the best information display of any bike computer that I've seen, but a bike computer that periodically glitches out and drastically under-reports speed when I go over even a minor road bump is not a bike computer, it's an unattractive handlebar ornament.

(I may some day put this on the MEC website, where I bought my dZ4L.)

A realization about Dantalian no Shoka

In his usual curmudgeon way, Aroduc has been grumpy about how the protagonists of Dantalian have just stood around for the past two episodes and watched while things happened around them. This has led me to a realization about Dantalian's genre.

Put simply, Dantalian is horror, not action. As horror, Huey and Dalian are our viewpoint to witness things and explain them, but they may or may not have to take any action to resolve the situation and return it to normality. In fact the running theme of the first four episodes is people who do something terribly wrong and are then destroyed by it (often through their hubris).

The first two episodes obscured this by having Huey act, but look back at when he had to act and what he had to do. In each case, Huey only had to act to dissipate the surface manifestation of the destruction (the out of control monsters); the actual responsible person had already been punished by the situation.

This may have already been obvious to other people, especially in light of Dantalian's ending sequence.

(Obvious disclaimer: Dantalian may yet change its genre. The opening has some suggestive bits.)
