I was replacing at least my second kitchen faucet because the water we have is high iron content.even though I have a whole house filter.  Yours has better quality than most others and easier to put mount to the sink and put together.  Hopefully it will last for better than 5 years and not be an issue to take apart.  The existing one rusted to the sink and I could not get the 1-7/16 inch nut off from under the sink.  The designer does not think about that issue.
