Product review (5 stars): Really aids in water flow compared to others. Still protects from backsplash and dampens sound.
Bought this to replace a more crenelated version (the version with big ridges) and this one works MUCH better. The issue with other baffles is that they don't allow enough water to flow through so water backs up in the sink unless you run the garbage disposal at all times to aid in water through-put. This one enables enough water to flow through and escape and also prevents food particles from escaping when the disposal is running (also helps to dampen the sound.) Recommend this design over all others.
