The fragility (and cost) of the gloves or coverings of the Touchbionics iLimb is legendary. No prosthetic hands smokes off expensive gloves faster.
That is in part because the relatively weak but lightweight motors will stop if the glove offers extensive resistance to the hand. So only the thinnest of gloves are given out by Touch Bionics for reasons of grip strength.
Only, as proficient user, that aspect greatly sucks.
Luckily, there is a bit of competition on the glove market - not as much as we wish to be, but some.
This reminds us of the times back in the days, when computer manufacturers issued proprietary video and monitor plugs. And when we got ourselves dip-switch setting modified video plug adapters to hook up Sun monitors on Apple or PC computers despite manufacturers' attempts to dominate device combinations. Growing into an industry that generally gives users only "their own" add-ons, consumables or other prosthetic extensions of any general kind, I was fast to see this as issue here as well.
And while the Bebionic hand's cosmetic glove allegedly may give Bebionic users a difficult time because it restricts or affects the thumb of the Bebionic too much, that glove is thick and sturdy enough to survive and yet sufficiently compliant to work with the iLimb. One will want it when one sees it, it is so good. So I got one because I wanted one when I saw one. Cosmetically, it sucks as it folds up and so on, but then, hiding one's handicap has not been approximated by the "bionic" trend currently happening in the realm of prosthetic hands.
The drawback is that the Bebionic covering's fingers are a bit too long for the iLimb. Here is how I fixed that.
