I heartily disagree. I've used Bioval bio BB's in the past, and so far they have been the best BB I have ever used. Never shattered, biodegraded well, flew straighter than anything else I've ever shot, comes in pretty cool colours too (tan, OD, black, etc.). It's a shame we can't get them here.
Also on the flip side, I've had plenty of standard non-bio BB's crack, break, chip etc in various circumstances both while playing and during gun testing/chronying and whatnot. Most of it seems to happen when BB's hit each other, or a very hard surface like brick or rock. Doesn't seem to matter what brand they are either, and I've used everything under the sun.
