Product review (3 stars): Works fine - thermostats could be more clearly marked, and spade fitting had to be installed by hand.
This unit was a direct replacement for the blown heater on my 13 year old Roper dryer.  I'd give it 5 star except there were two issues that I thought were significant enough to warrant a downgrade.
1st, it wasn't perfectly clear to me which thermostat was which.  The two coming out looked different.  The two that came with this kit looked the same.  There were some markings, but not as clear as they could have been.  Further, the thermostats are the same size and can be installed either way.  If you install them backwards, the overrun thermostat (high limit, non-resettable cut out) will be at the bottom, where the air comes in, and the run thermostat will be at the top, where the air is going into the clothes area.  The result of that is PROBABLY that the run thermostat will trip more easily, and the air entering the dryer won't be as hot.  You also won't have overtemp protection if the top end is running hot.  I'm unsure, but this seems like a safety issue.  Should be clearly marked, and, preferably, incapable of being installed in switched positions.
2nd issue - the "spade" fitting that came with this was the wrong size, but they included the correct size.  Problem is, I had to cut off the wrong one, strip the wire, and crimp on the correct spade fitting.  Not going to lie, that makes me uncomfortable.
I'll gladly pay an extra few bucks to get a unit that comes ready to install, matched to my machine, and with thermostats properly marked.

Does it work?  Yes.  Dryer is as hot as ever.

If you're reading this and you are considering buying JUST the heater, don't do it.  If your heater blew out it may well be because your run thermostat is running too hot, but not hot enough to trip the high limit.  If you replace only the heater, it will run hot and may burn out in a few months.
ALWAYS replace both the run thermostat and the high limit cut out when you replace the heater.
