## Customer feedback

Customer feedback supplied for this listing describes drawer slides, not these rear mounting brackets. It reports favorable impressions of slide quality, installation and operation, alongside mixed comments about soft-close force and sturdiness, including reports of ball bearings falling out. Those perceptions do not establish bracket performance or compatibility.
