Product review (3 stars): Many sellers are selling cheap aftermarket parts
Although this page description makes it appear that this is a real OEM (Whirlpool) part, many of the sellers are selling cheap aftermarket parts.  The one I received had no part identification or markings on it, no electrical ratings, etc.  The part was also clearly inferior to the original Whirlpool part.  It would be very easy to swap the original Nichrome wire with stainless steel, looks the same, but you would get much less heat from the stainless steel.  The terminal block is also cheap on the aftermarket parts, which could lead to a fire.

If you buy from the Amazon Marketplace be sure you buy from someone that specifically claims it is an Genuine Whirlpool part.  Considering the real thing is only ~$35, I would not jeopardize my safety and risk a drier fire to save a few bucks.

I gave 3 stars because the real thing should be fine, just a lot of shady dealers in the market place, including some that are "Fulfilled by Amazon".
