Query: Do not buy this item for V3 Razr

I ordered this packet to get the M16 tip to charge the new model V3 Razr, which will not charge using the older M15 tip. The picture for the package shows the M15, but the description says it includes the current M16, which will also work with older Razrs. The first package that arrived had the M1 and M3 tips, but no M16. I returned it to Amazon with an e-mail explanation of the problem. The replacement set I received also contained only two tips and no M16. I e-mailed Amazon and they responded quickly, acknowledging that they are have a larger problem with this set than they realized. They refunded my purchase price. This is not Amazon's fault and they have responded quickly to the problem. I can't find out how to get an M16 tip on Kensington's web site, so I ordered the USB PowerTip to be able to charge my phone from my notebook.
