Well built
Very good quality and works well

Excellent
This is well worth the price. For a six gallon batch of brew, it chills it instantly to pitching temp with the garden hose water.

Huge upgrade from a coil chiller
After 8 years of using a coil chiller I finally got a plate chiller. World of difference. It's so much faster. Wish I bought one 6 years ago.

working well so far
I am using this as a oil cooler running engine oil and engine coolant working great so far and very efficient. a little on the heavy side but compared to aluminum can't complain

definately good quality
This heat exchanger is a bargan i was unsure if it would be big enouph to use for hot water to my water heater with my outdoor boiler, but I have very hot water and as much of it as i need now it definately will keep up with my water heater actually far exceeds my actual gas water heater. I will buy another one when my bathroom in my polebarn is finished and debated having one for a shop hot water spigot for washing equiptment.

Cools wort, doesn’t leak, seems legit.
I use this as a wort chiller. When I switched from an 8 gallon kettle to a keggle, my copper coil was physically too small to use and still have the connections outside of the kettle. After I had a hose blow off my coil and get tap water in my nearly chilled wort, I decided to find a better way. The nice thing about a plate chiller is that it is so small that you don’t need to handle or store it. I have mine clipped right next to my kettle, and all I have to do when I want to use it is hook up my hoses. I’m going to exbeeriment with using it during my eBIAB mash to heat sparge water to mash temps. As far as cleaning goes, I’ve found that it really helps to alternate back and forward flushing hot PBW through it until it runs clear, then repeat with water. Time will tell how clean it stays. As far as performance, it gets my 5 gallon batch of wort from boiling, down to pitching temps in about 30 minutes on tap water. I was hoping for faster cooling than that, but I’m going to tweak my technique a little and see if I can avoid recirculating it back into my kettle. If I set it up right, it should come out at pitching temperature. That should shave some time off my brew day.

Works ok if only for liquid only uses. Not for brewing, particles get stuck and is hard toto clean.
Great for pure liquid movement. It's a bear to clean if you use it for brewing, I went back to a copper coil wort chiller for brewing just due to cleanliness.
