titanium upper and lower elements?

Since this heater changed from residential to commercial I believe Marathon switched to titanium elements for both upper and lower. Can you confirm this because the home depot description is still showing just titanium for lower.

Rated 1 out of 5 by from DO NOT BUY THIS! DO NOT BUY THIS! I would give it zero stars if I could. We bought this water heater about 3 years ago and no longer works! Now we have to find an entirely new, more reliable water heater, because the labor that it cost to fix it even if we did get the part replaced is just as much as getting a brand new heater! Our OLDER version water heater lasted 17 YEARS.
