Have only had one reported case of a pip (i.e., the epoxy that fills the hole drilled for each spot) falling out. This can occur due to rapid changes in temperature. For example, storing dice outside in below zero temperatures and then placing them on a table in direct sunlight. Precision dice as a whole are not immune to this. Moreover our custom precision dice are manufactured to the same standards as precision craps dice used in casinos. The only difference in the process is that our dice are ball-cornered to permit better action, or rolling, just as precision backgammon dice are.
The ultra-thin foil used for monograms on casino (and BattleDice) is thin for a reason. While it can wear, especially if deliberately scratched and treated to sweaty mittens for days on end without cleaning (salts and acids will corrode/wear down the foil over time), the weight of the foil is so minuscule that it will not impact balance.
More important for ensuring balance is that the dice are "square" on all sides to within a 1/10,000 of an inch, and that the cellulose acetate removed for each pip is replaced with epoxy of the same density.
Bottom line is that BattleDice are simply precision backgammon dice with custom foil monograms. They occasionally have different coloured pips, although this is no longer exclusive to our BattleDice, as we have been carrying
precision backgammon dice with colour pips for two or three years now.
Regardless of whether you like the look of BattleDice, or not, I would strongly encourage players to purchase one pair of precision dice. A set of white and bright-red precision dice will not break the bank. Andreas (
Trojan Games in Sweden) carries our precision backgammon dice, if folks think that our shipping costs to Europe ($10) are prohibitive.
