I am concerned about the shipping packaging of the product! Although it arrived in a timely manner the packaging appeared to have been 'through the wringer' (handled roughly). I am not able to use the cartridges right away and am somewhat concerned that when I do they may have had internal damage and not perform properly. The exterior of the cartridge appears to be OK as it was in bubble wrap. So to make a long story short I am a somewhat dissatisfied customer. Product appearance and packaging, I know, doesn't always reflect performance but does set a customers mind at ease about reliability when the packaging arrives unscathed.
