Product review (5 stars): Relatively easy installation
All 4 agits were broken. Easy to disassemble and replace. Watch a video to make ease of installation. Most difficulty is in re-installation of the part. Make certain of allignment to avoid breakage. Took about 10-15 minutes to disassemble and re-install. No repair person required. Unit runs well again. Plastic agits appear to deteriorate due to age and collapse from use. Parts fit well.
