Product review (5 stars): Try these if your washer is walking
Had lots of trouble keeping my LG WM2016CW washer balanced and it would often start "walking". I found one of the plastic lock nuts had broken and the bottom of the legs were pretty worn so ordered these replacements. These appear to be an upgrade from the original legs. The rubber piece is somewhat larger and there is a steel lock nut instead of the plastic one.

After installing the Washer seems to be vibrating less and hasn't moved at all. If that changes I will update the review.

It's been over 6 months and doing great.
