At first glance, the Zebra DelGuard looks like the popular Uni Kuru Toga and offers a similar lead-break-reducing feature (though without the point protection). The clear plastic section is molded with a similar grip and the body is black-ish and slightly thicker than the average mechanical pencil. Inside, though, is what appears to be a much simpler spring-mechanism that promises to keep your lead from snapping. Does it really do enough?
The body is a simple, matte-black tube with a small logo just before the center-band. On the back is an attached clip with some printed information, and a chrome click-button cover that easily slips off to reveal a thin, white eraser that easily pulls out to reveal the lead tube. The (grip) section is a black, translucent, and slightly slippery-feeling plastic with some ridges for grip and a slight slope down to a small metal lead pipe.
Performance of the main features of (mechanical) pencils is good but not outstanding. The clip holds well and doesn’t rip fabric; the eraser removes marks handily with minimal shavings (and a little bit of smear); and the lead is average verging on soft (it is fairly smooth and I like the .5 size). The actual DelGuard system is a bit more dubious to me, though. It’s basically a few springs that allow for a huge range of vertical motion for both the lead and the lead pipe. This means that if the user bears down vertically on up to a few clicks-worth of lead it will simply retreat into the pencil and not break, even with a considerable amount of force. Unfortunately, I write/draw at an angle, and that is apparently extreme enough to mean the lead will snap with an amount of pressure I usually associate with a lead snapping, since the system only relieves pressure vertically. This isn’t really an issue for me; I write/draw softly enough that lead breaking isn’t something I worry about. But it has the same problem for me that the Kuru Toga has; that is, with my writing style, the system doesn’t work, making it completely pointless. This pencil could not have its cushioning springs and be exactly the same experience for me.
So, as a pencil, it’s a good writer that might be moderately overpriced (it’s more expensive than the Kuru Toga). I’ve gotten other pencils with a similar writing experience for a similar price, but this is nothing special and I personally wouldn’t get it over less-expensive Zebra models, especially since the grip doesn’t feel too good in my hands; I haven’t had it actually slip, but it just feels slippery. If you really have a serious problem with your leads breaking, this might be worth looking into, otherwise it’s just a tossup with similar models.
