First of all, I have to say that the product is exactly as described in terms of dimensions. It is made by a Greek company and that counts (I will explain later). Installation and cleaning are extremely easy. It is the best product available for €37 in terms of quality-price ratio. That's all regarding the product.
As for the companies Finezza Home (the store where I purchased the product) and Elvit (the manufacturing factory), they were EXCELLENT. I ordered the product and it arrived quickly, despite living on an island. In the package with the accessories, half of the plastic was missing, as seen in the photo due to a machine error during cutting. I was disappointed because I thought, "How am I going to solve this now?" Without wasting any time, I called the store and they immediately contacted the factory. They sent me another package of accessories within a few days. When the package arrived, there was a mistake made by the shipping company and there were recipient charges. I called the company again and within half an hour, they contacted the shipping company and I was able to receive it for free. Of course, the package did not contain exactly the same accessories, so I had to call the company again. Ms. Eleni, who assisted me throughout this process, was a PROFESSIONAL. Within fifteen minutes, she had already contacted Elvit and sent me photos and instructions for the new accessories (different but better and reinforced). Here, I want to mention what I said at the beginning about the Greek company, that when something is manufactured here, there is the possibility of being supported in such matters. If it had been from abroad, I don't think I would have solved it even in a month (if at all).
I could have just mentioned all of this and simply written "excellent service." But I believe it is worth writing a good review when we encounter professionals. WELL DONE!
