Query: good design, bad materials: doesn't last due to fragile o-ring&plastic joint at swivel

good design, bad materials: doesn't last due to fragile o-ring&plastic; joint at swivel.almost all plastic; sometimes hard to pull from aerator setting to spray setting, which gradually weakens the swivel's o-ring seal, will not re-set properly or for very long (i.e. the problem returns). I bought five for multiple sinks and friends, am now on my third one in 8 months. I recommend the getting one with a stronger swivel joint and a gentler release on the aerator-to-spray mechanism, such as:ELKAY LK371 Adjustable Swivel Faucet Aerator or Danco 36325B Swivel Aerator and Sprayer, though the second one uses plastic too, hence the lower price.
