First elected: shower was the New Tempesta (was also on packaging), but this was broken. Requested replacement and Tempesta 100 (old version), even though the label with the item number, the version of the New Tempesta displayed. Requested re-replacement and again 100 received the old version Tempesta (again with the products Stickers New Tempesta). I then spoke directly to Grohe. Tempesta 100 is the previous version of the New Tempesta. The new version has some improvements in mechanics and design. So make sure that you really get the "New Tempesta". On the product image here at Amazon, the correct version is displayed. Additionally "Tempesta New" on the packaging. Even the Grohe Logo is in the new version different from incorporated as in the Tempesta 100th
