Rating : - good "non-complainable" gift item! :)
well, if you do buy it for someone, chances of them complaining against it will be minimal for sure. But like most people here have written, Pray they are never in a situation for it to be used. Sometimes, it can just be another one of novelty items that end up in your workshop.

I decided to try out the effectiveness on a window pane that already had a deep crack across it, and since it was going to be disposed off, decided to use it on the same, the hammer would create a localized stress point that increases and the shattering of the pane would occur after a few hits. But these are ideal conditions with all comfort and angles for hitting, unsure of real time conditions and if its all the same, rather not find out.
