It's awesome!!! Japanese...I don't expect anything less...practical and does the job just fine! The water is very light and tastes great...the filter is super easy to change and so is the installation!! It comes with various adapters inside that I believe fit all faucets!
I also bought one as a gift for my best man and for a friend of mine when there was a 50% offer at €69 while I had bought it for €139!
No second thoughts!!
P.S. I haven't taken the water for analysis yet but I will and I'll get back!!

I bought it on offer for around 75 euros. The water is much higher quality and there is a noticeable difference compared to other cheaper filters I had in the past. It has an electronic indicator when the replacement part runs out. This costs around 29 euros if you look for it, and it needs to be changed every 1-2 months, quite frequently. For the installation, I needed the store's technical support, which was immediate and helpful

Build quality is quite good, I don't know why people write otherwise here! Installation was a bit tricky on my faucet because it needed a rubber ring and the blue component, so I took one from the others and used it, but in the end everything was fine. Let's get to the reason someone buys it—the water quality before and after... I put tap water and filtered water in two identical glasses. The test really surprised me! I thought it was just my imagination... I did the same blind test with 3 people and in all cases the filtered water won! The tap water tasted sour and earthy to everyone!!! What have we been drinking all these years!!! Let's go to test number two, again two identical glasses, this time with bottled ALPHA water without them knowing which is which. Everyone preferred the bottled water... Purchased for 79.90 BF, and 29 euros +1 extra filter! Which I still think is a lot!

So far it is flawless. The screen showing the liters you have used is very helpful, as it only measures the liters filtered and not the rest of the flow.

Very good filter. You immediately feel the difference in the taste of the water. Easy installation, cleaning of the device, and filter replacement. In small sinks, due to its size, it might complicate things a bit. At 90 euros, I think it's worth it. Beyond that, I would consider the alternative of the same company for an under-sink filter

very good filter, I don't have measurements of course, but being Japanese I trust it, the water looks okay, for someone to be 100% let them do the measurements.

Excellent filter. I bought it due to pregnancy in order not to buy packs of water and to drink quality water. It is very good, easy to install, and the water doesn't smell like chlorine and iron, even though it is supposed that the water from Nea Smyrni is drinkable.

Easy to assemble, even though it didn't have instructions (referring to a faucet with internal threading). The water tastes like the bottled one I have been buying for so many years and has no unpleasant odor. It also has an extra adjustment like a shower head which is very useful.

Excellent communication with the company for explanations. Quality? I don't notice any difference at all with the water I was drinking without a filter, the only noticeable difference is that when I lift the glass of water under the kitchen light, I see hundreds of small particles floating like threads. I bought it at half price during the Black Friday period

Good in taste, the water from the filter. I think, however, it was a little better than the torrayvino I had before. Anyway, it has nothing to do with unfiltered water. No smell or taste of chlorine.

Problem with the connection, the neck of the replacement part is small and when a sealing rubber is added it does not screw easily onto the faucet and there is a leak. Water quality excellent.

It has an indication for how many ml of water you add (from filtered water) and for how many liters are still remaining, with a click (press a button) you can change and see. Also, when you run it too much, it warns you by flashing.

Mine has normal instructions in Greek and is very user-friendly and easy to install. Quite good water quality

To me it came with instructions in Greek and 1 month later I am quite satisfied as the difference in water quality is noticeable

Although the money seemed like a lot from the first day of operation, I think it erased any bad thoughts. The difference in water quality is chaotic. Initially, I can now drink water without feeling heavy

I am very satisfied with the quality of the water that comes out and with the flow. I think it's worth its money

First of all, let me say that my package had normal instructions in Greek. As a device, it is quite high quality. I don't know if it's worth the money because I'm using it for the first time. So far, though, it produces very clean water without any particular tastes or smells. Just as it should be

Contrary to what I read here, the product is of quite good quality both as a device and in terms of its materials, but mainly it has instructions for use in Greek

The quality and appearance of the plastic could possibly be better for the price of the product, but it does its job very well because we had a lot of cloudiness in the water that no longer exists

For the money of the offer that I had bought it, it definitely worth its money. It only works in the summer at the countryside and it does its job quite well so far. At the regular price, I don't know, maybe it's a bit expensive, but the 80€ that I had bought it for definitely worth it

I have a simple battery with a hot-cold mixer in the center and it fit perfectly without needing any additional parts. The water comes out crystal clear without any plastic taste. The quality could be a little better, at least externally, but it's worth the money

And the product is advertised and has "many laurels" and even awards from Red Dot Design. Here the positives of the product end because as soon as you hold it in your hands, you realize that the quality of the product is different from what is shown in the advertisements (especially the adapters that fit on the faucet), very poor quality plastic. But the worst part is that there is NO other language besides Japanese in the product's user manual. Evident obstruction by the Ministry of Commerce!!
Very bad product..
