Bought it twice. The first time, after 6 months of use, it cracked and opened at the label point, along with the threading of the lid, meaning the point where it opens in two to change the cartridge. I assumed it might have been a coincidence and bought the same one again. In 6 months, it broke again at the exact same point. Without having increased pressure and without the filter being clogged. Not from excessive tightening either. Its quality is obviously fake and due to its lifespan, I give it one star. Money wasted, so I will try another brand.

Easy to install, I have been using it for years and I am satisfied. The only negative thing is that the replacement costs almost as much as the entire filter.

I honestly bought the product to filter out dirt and chlorine! Lately, they have been doing construction work all over the city where I live, and everything has been affected by it.... I could see the dirt in the bathroom and couldn't believe it! Since I didn't want to install it in the main water supply for some reason, I decided to try this one! I wasn't really concerned about the claims of softer hair and skin sensation, because as I mentioned earlier, I mainly wanted to avoid the dirt, but I have to say that I noticed it.... INDEED, my hair is softer after showering than before using the filter.... and I have to say that you can also feel it in the water.... I should also mention that there was a slight decrease in water pressure, which is logical!
Now, I didn't like that it is big, so when you turn on the water, it flows from the faucet and not from the showerhead, and it falls on it, so you can't, for example, fill a bucket.... obviously, they thought of that and added the corners you see, so you're covered.... I needed a little Teflon tape for my faucet, but I believe they can make them thinner!
Finally, it says it's for 2 adults, and it lasts for 5 months, so for one adult, it lasts for 10 months, or it needs to be replaced... I have no idea!
