Product review (5 stars): $25 and 15 minutes later...
The part was a direct replacement for my Roper dryer (which is made by Whirlpool). It took longer to take the back panel off the dryer then the replace the actual element.  As another reviewer said, there is one small part you have to take off the old element but it's straightforward. So glad I found this part and did it myself then paying a repair man an obscene fortune to fix it.
