I use the pitcher, and I am very satisfied, not so much with their shipping method by the company GSL, with a cost of €10, (much higher than with many shipping companies), without receiving information about my shipment, having to contact the company directly twice to know about my package, which they left at a pickup point without any direct notice to me from GSL or the company I had spoken to days before stating that I had no information since my purchase. GSL is one of the worst shipping companies and the most expensive, I hope they start using another. For this, I give 3 stars, good product but the shipping issue is a hassle, high cost and poor service. This is not my first purchase with Alkanatur.

The instruction manual is not clear. When the filter has been activated, it does not explain the next steps to use it. How far should it be filled with water? And should the pitcher be filled or is it from where the filter is? Because then it filters very little water, half a liter. Not one and a half liters as published.

Actually, I am happy with the pitcher, but I have only been using it for a month and a half and for the last two weeks the taste has changed a lot, now it is very bitter and not pleasant to drink. The filter is supposed to be changed every 3 months, but after a month it has stopped working well, it seems.

The order was quite delayed and when it arrived, all three filters were broken, just opening the package all the microbeads from the filters spilled out. When I tried to contact them, they did not answer the phone (not even during their working hours), I had to resolve it through their email. Bad experience.

The intention is to promote health and the pitcher is made of plastic. Also difficult to refill and clean. It's not worth its price. The filter does indeed remove flavors from the water. That's why I rate it higher.
Translated reviews
Response from Alkanatur
Hello yes, but our pitcher is made of 100% toxic-free plastic. It is certified by Dr. Nicolás Olea, an expert in endocrine disruptors, so it is a completely safe container. We have the certificate posted on the website if you want to check it. Most plastics we acquire from bottled water contain toxins that migrate into the water.

I like the taste of the water once it goes through the filter since in my area it is very hard water and I think that with the pitcher I have managed to improve the taste, however the pitcher seems to me to be of poor quality, the lid stays half open and does not look like it has great durability. I expected better components. I would prefer it to be made of glass or similar.

I like the product but I had to call because it was taking a long time to arrive and from the time I placed the order until it went to the distributor 2 or 3 days passed, I understand it should have been in 24 hours. I am also not surprised that the survey is now being sent 3 or 4 months after the purchase. I believe the quality of the product deserves a faster and more careful service.
