In my case the faucet was very hard to install as it required reaching behind the deep apron sink to tighten nuts. I had to hire a handyman who's better tools than mine made the difference. Typically I can install stuff like this myself. It was the location of the faucet only that made it hard, otherwise it would have been easy.
Great water filter for small spaces. Easy to install. Big difference in water taste. Wish water filter was faster but overall good option if you can't use an RO system.
