We installed it in about 15 minutes. The hardest part was getting under the sink. Very, very easy to install and set up, and our very hard water tastes great - now it tastes as good as filtered water from the fridge. It comes with everything you need for installation - stainless steel hoses, wrenches, clear instructions. In addition, this company produces filters. Often there are no filters available for these unbranded filters, but there are some Wingsol filters. I've bought a few to replace when the time comes, just in case they go out of sale in the future. Great inexpensive but high quality sink filter. Filters are available here: https://www.amazon.com/WINGSOL-Replacement-Material-Chlorine-Contaminants/dp/B0871YBKVT/ref=sr_1_8?keywords=Wingsol+replacement+filter&qid=1636289313&sr=8-8
