I have bought before, but during all the promotion days on the website it was impossible to add anything to the cart, it got blocked and nothing could be added... after the promotions ended and returned to the normal price, coincidentally it can be added and bought perfectly. What a scam the promotion periods are.

Just to comment that GSL does not deliver to the doors of apartments in buildings without elevators, they ask you to go down and pick it up at the building's door, which is a problem for people with reduced mobility. The bad note goes to the transport company, the product is excellent.

I do not know to what extent everything the jug does is real, but I do notice the change in taste. What I do not like is the quality of it, the plastic seems fragile, and it accumulates a lot of dirt.

The jug is ideal, but the top part for pouring the water is too small, only a little amount comes in and you have to wait for it to filter to fill it more. What a shame.

I ordered a replacement filter for my jug, I received a complete jug, with its corresponding replacement. I informed them of the error. And besides not thanking me (which for me would have been easier to stay quiet and keep the jug worth seventy-something euros), they told me I had to wait for them to come pick up the jug and deliver the filter. I mentioned that I urgently needed the filter, since the error was theirs and the filter inside the jug is the same as the one I had ordered, if I could keep that filter and return the jug, as I obviously did. But gentlemen from Alkanatur, first you thank the customer for reporting the error, and then, the customer should have as few inconveniences as possible. In summary, negligent in order preparation, unkind and unhelpful.

Greenish appeared on the edges. I sent an incident and they tell me to wash it
Translated reviews
Response from Alkanatur
Hello, Yolanda:
We regret that this situation has caused you a bad experience.
The appearance of greenish color is usually not due to a defect in the jug, but to a natural phenomenon that can occur when chlorine-free water remains stagnant for several days, especially in hot weather or if the jug is near a source of light or heat. It is a similar effect to what can be observed in ponds or containers with stored water for a while.
To eliminate it, we recommend performing a deep cleaning with a small amount of diluted bleach in water, letting it act for a few hours and then rinsing the jug thoroughly.
Additionally, to prevent its appearance, we advise performing a weekly cleaning of the jug. If you also observe whitish residues on the walls, you can use a mixture of warm water and vinegar in equal parts, letting it act for a few hours before rinsing. This helps to eliminate mineral deposits and restore the shine of the product.
We regret that our instructions did not meet your expectations, but this is the usual recommended procedure for this type of situation.
Best regards,
Alkanatur Team

The material of the lid is too fragile and unstable. When filling the jar, the lid through which the water is introduced lifts very easily and releases all the water even when almost all of it has already leaked out. Additionally, after just one month of use, the spout through which the water is released broke.

When putting the lid on the jug, the water filling spout is slightly raised. This is due to the pressure that the vessel exerts on the entire upper lid assembly. One more thing: if I overfill the jug, when pouring water into a glass, the unfiltered water that remains before the filter comes out through the filling spout.
