It is environmentally friendly as it is a simple packaging. I think that quality is quite no problem on appearance. However, due to the nature of the product, it may not be real quality unless it is several years.
We used it on the hot water supply pipe side by connecting the G13 screws to the water tap. I thought that it was nice to be easy to bend though the installation work was carried out by bending the blade flexure somewhat. I bought the length of blade blade 700 mm, so I felt a little cheaper than purchasing at another company. If you have the opportunity to buy again.
