Product review (1 stars): Definitely better off getting Genuine FSP part - not this cheap knock-off
UPDATE Oct. 2014
Definitely find a genuine FSP coupler and avoid these cheap knock-offs - the FSP part I found over a year ago has been flawless.  The cheaper polymer in the knock-off brands failed several times where the FSP has not failed once!  I got them for about $5 a piece and was well worth it not to tear apart my washer again.  If my FSP ever breaks, I'll come back and post here to hopefully help you guys/gals out.

UPDATE Sept. 2013
Another broken coupler - I found many posts that suggest buying an genuine FSP replacement part and not the generic, cheaper parts...probably made in China.  I found a 3-pack of FSP couplers on eBay for $15 so will give them a try (FSP is the OEM brand of parts inside the washer now - take a look if you doubt me).  I checked my transmission, pump, agitator, and motor - all spin freely and are not locked up.  Bottom line, go with genuine parts when quality of plastic matters, this part transfers all the motor force and thus needs a properly engineered polymer to carry the load.  I am also going with the newer metal insert OEM FSP part too - the 3 tiny plastic tabs/teeth will break off WAAAAY before the metal insert strips/rounds the motor shaft...think about it.  I'll update this review if the metal FSP part fails...and quietly eat my words!

UPDATE May 2013
Coupler has broken - seems that a more brittle plastic polymer (i.e. cheaper) was used in this coupler and it failed along the center hole.  The washer transmission is smooth and non-binding and is used with very small, light loads. The rubber used in the black isolator also had several tears and stress cracking as it was much stiffer than the OEM part.  It only lasted a few months of very light use (however, it was only 3-4 dollars).

Probably worth it to buy an OEM part for a bit more and save the time of a second tear-down and fix.

Original Review:
Looks like an exact replacement and fits nicely.  Should provide years of use (the OEM was over 6 yrs old) and will fail properly as designed instead of destroying the washer transmission or motor shaft.  I like this better than the metal reinforced design - again, a cheap fail safe that protects more expensive parts.
