I have used the 30 plate version about 12 times now. It is fantastic.
I use Bobby_M's hop filter that I built. It is probably one of the absolute best additions to my system. I just brewed a 12 gallon batch on Saturday with 9oz of hops in the boil. Pellet hops, added directly to the boil. I would say that less than 1% of the solids in the kettle made it to the fermenter. It is AMAZING. I used to have some clogging issues with my plate chiller. No longer. In fact, when back flushing it, I did not see any solids coming out. Previously there was a ton. I now consider the filter nothing short of essential on brew day. I was using a false bottom previously.

Other notes:
1. To prepare the chiller, I place it in an extra pot full of water and boil it on brew day. Super easy, fast, and 100% effective.
2. To clean it, I just put the hose up to the port and flush it out. Reverse a couple of times, then hang from the edge of a bucket to dry.
3. When using it, I make sure to run boiling wort though it for a minute or so before turning on the garden hose water adding an extra sanitation step.
Flowing at full steam with 70F garden hose water, the chiller brings the wort down to 80-85F as fast as I can pump it out of the kettle.
12+ brews though it with no issues.
