Product review (5 stars): Could be good or bad if they last as long as the ...
Real Whirlpool/Maytag parts.  Could be bad if they last as long as the originals.  I had about 6 years on the original ones.

I believe I saw these have an updated seal which hopefully make these last longer.  Do yourself and your new bearings a favor and buy the bearing press tool or make one.  Don't be the person complaining your new bearings are brinnelled and noisy and not telling everyone you hammered them in.

There are a few decent videos on the internet you can watch to get familiar with the replacement process.  Plan to spend about an hour on this if you are good with tools.  More if you are meticulous or not mechanically inclined.
