Bad taste. Great design, bad cartridges.
This seems to be a very well made device, a large improvement to the Aquasana countertop I have used for years. It is solid, seals tightly,and the aerator is high quality.
However, there is a major issue with the filter and the water is not drinkable. It smells and tastes like dead fish. I tried the replacement filter it came with and it's just as bad. I just ordered more replacement filters, the standard, as I originally ordered the alkaline filter. I hope it is just a batch of bad cartridges, because I really want to be happy with this product. I have yet to find out what LCF will do for me.

Convenient, easy install and improves the taste of your water.
I was a water dispenser user and it was costing me more than it should for water. I decided to do some research and decided to try this filter. It has made me a believer. Our water tastes some much better. Our food has improved in flavor and it’s economical. Installation was quick and easy. Water flow is perfect.

Good quality
I received item on time but had to return it. Not because it was poor quality but because the adapters wouldn't fit my faucet.
They sent several adapters.
It looked like a great product but for my situation it just didn't work.
I was refunded promptly.

Good filter
This is my setup… I like the filter. But this filter only has connection to the faucet. I spend extra 40 to get the hose, valve. Online you can get it cheaper

The smart faucet comes with an LED indicator and touch controls, allowing you to achieve quantitative water intake without watchful waiting. It can also real-time monitor the TDS value and alert you when it's time to replace filters.
The tankless design has fewer pipes and installation steps so you can install this undersink RO system with basic DIY skills, as it includes an easy-to-follow instruction and full accessories.
The filter is certified by SGS to reduce over 1,000 different impurities including TDS, PFOA, PFOS, Chlorine, Fluoride, Arsenic, Lead, and more, while the auto-sensing LED function ensures water safety.
Common RO systems can reduce some beneficial minerals. This undersink reverse osmosis water filter features an alkaline remineralization function that reintroduces beneficial minerals to the water, ensuring a balanced pH for healthier hydration.
This 1200GPD large-capacity undersink RO system delivers a flow rate of about 1200 gallons per day, which is ideal for everyday use. Compared to the traditional tank RO, it achieves faster and more space-savings, while making sure that every drop of water you get is fresh and pure.
