I have been using it for 3 months now. It has a difficulty in movements as it doesn't seem very flexible. I believe it will improve with use. It seems to be well-made

I just received it and immediately noticed that the diameter is smaller (not the length). I don't know why they did this, but it has a smaller hole for the water to pass through. In the end, it works great, looks high-quality, and I believe it's worth its money! As for the length, which I wanted, it served me well!

I have been using it for a few days so I cannot judge its durability over time. What I can say is that it is of very good quality and it is flexible. I don't think it will give me any problems in the coming years.

It has its good sides, it is durable and does not damage the bathtub, however, it is not very stylish like the metallic one

For prospective buyers, I have to mention the following:
If your bathroom faucet is low or your shower base is high, but the "common" spiral with a length of 1.5 meters covered you perfectly and now you are thinking of buying this one from Grohe... well, do yourself a favor (and your wallet) and get the one with a length of 2 meters.
Because this one is more rigid compared to the common spirals, it does not bend as much as they do (so the length is "cut" that way). Unfortunately, you cannot realize this, neither when you take it out of its packaging, nor when you hold it in your hands and stretch or examine it in general. The disappointment comes when you install it. Personally, I couldn't accept this borderline situation and ended up buying the 2-meter one again. In terms of quality, it is top-notch with metallic connectors, etc.
Since I had to learn the hard way, I am writing this review to save you from it if you are skeptical about the length. Lucky you!

It's worth its money. A little hard at first but ultimately proves to be very good. It doesn't ruin the aesthetics of the bathroom and shows that it remains sturdy even with daily use.

I have been using this spiral shower for many years....
It is really worth its money, it doesn't scratch the bathtub, tiles.
It doesn't break at all!! I changed it when I moved houses and the new house had the classic one with the metallic coating, which breaks over time, and I returned to this one which I have had for 8+ years.
The only thing that might surprise you is that it looks like a rubber hose but aesthetically it is much nicer compared to the metallic ones.
The only downside I would mention is that it is not as flexible as the other one, but if it gets warmed up by the water it becomes flexible. However, the flexibility never bothered me.

Appearance-wise, it is very beautiful and aesthetically enhances the bathroom on its own. As for the construction quality, I cannot judge yet, but it seems much sturdier than the standard spiral. I will return in 2-3 months for further details.

Addition:
After about 8 months, the spiral has softened a bit. It has not shown any signs of wear anywhere. I say this because I had replaced 2 spirals within a 6-month period. I would recommend it.
