Supposedly conceived of by a Swedish inventor, the Digigrip serves a very specific purpose. From what we gather, it can be attached to a bag and works like a regular handle. Once you lift the bag using it, a display will show you how heavy the carryall is.
On the surface, this appears useful for frequent travelers, but we have our doubts. For one, how does that thing attach itself to the bag? The product description page (which oddly lists a Hong Kong contact address) sells a hollow punch for making holes. That, coupled with pictures showing only fabric-based bags, leads us to conclude that you have to make holes in your luggage to use the Digigrip.
Still, those who frequently find themselves paying excess baggage fees may find this gizmo useful. The Digigrip site lists it for sale at 19 euros (about $28), but approach with caution--the poorly designed Web site doesn't exactly inspire buyer confidence.
