I saw a set on display and to me they looked a little oversized. When I first saw pics of them I thought to myself they would be great for working under a dash. But after seeing them I don't think they would fit in most of the dark places they could be usefull. And then things like batt life, what kind of batts, are they replaceable, are they as strong as reg pliers, can you warrenty them come to mind. I would put them in the gimmicky cattagory, kinda neat to look at but not really usefull.
Think of all those light up screw driver handles, we've all gotten one as some time or other... Have they ever really been usefull? lol
