I love this filter system!! It was so easy to install, even though I had to switch the nozzle on the sink. Once I installed the filter, letting it run for 5 minutes was a waste of water, but for the sake of the filter and instructions, I allowed it... It's also kind of a hassle to remember to let the filter run for 5 seconds before using, but that first taste of the previously disgusting tap water that exists here on FL was worth it! No after taste finally and I can finally stop buying so much bottled water!! The good definitely outweighs the bad with this one! I'm ecstatic!
