Product review (5 stars): If you're on the fence between this and a repairman, buy this!
Worked perfectly & saved us SO much money over having a repairman come out and replace our broken element (or, buying a new dryer, which is what we were also considering)!  Watch the video that others mention - it walks you through the entire process and was not overly difficult. Has been installed now for a couple months and is working fine.
Interestingly, the box it arrived in was literally the largest box I have EVER had anything shipped to me in...a little bizarre that the element needed such a huge box - but it has served as a great boat/cave/rocketship for my preschooler ;)
