I bought Force one from Gym and Fitness(from ebay) end of 2011..
paid $170+21 shipping.
it got knocked around a bit during transport..
the ad said 12kg case, then 4, 4, 4 and 8kg plates, for 32kg total
weighing them up, i got 13kg case, 2, 3, 3, 4 and 7.8kg plates, and a total of 33kg! but it did come in a "proper" Force cardboard box.
I see they've now changed the ad to be
Kettlebell with no internal weight plates: 12.5kg plates 3kg, 3.8kg, 8kg, 2.8kg, 1.9kg
construction looks similar to the IE one, and both internally and externally, I can't see any difference, apart from the paint colour.
Force one also overlaps at the seam, but the handle is finishied very well, so is very comfortable.
CCM, have you measured the weight of the individual plates?
if not, would you mind doing so at some point?
they might be an identical item... or the IE one has evenly graduated weight plates... either way, i'm still happy with the Force one
