Product review (1 stars): DO NOT BUY!!! CHEAP KNOCK-OFFS!! READ ALL REVIEWS!
AVOID THIS JUNK!  These were a complete waste of money and the time to disassemble and install.  They were MORE NOISY, and started to disintegrate within 5 DAYS.  I should have read the reviews--I bought the LG OEM rollers after all and returned this JUNK to Amazon.  The OEM rollers were immediately QUIET.  The difference is qualify is obvious; the OEM roller rubber is like a car tire, whereas these cheap rollers are like a bicycle inner tube.  Shame on Amazon for selling and fulfilling this JUNK to its loyal customers!
