I would buy this product again
I installed the mixing valve according to the instructions and it works as it was advertised. After a few uses I was able to dial-in the temperature at a safe and comfortable setting.

Great Product
Im A Huge Fan Of How Easy It Is To Set Temps. Ive Installed 6 Or 7 Now . With The Included Temp Chart In The Manual You Can Set Output Temps With Great Accuracy. Doesnt Hurt That Its Price Is About 30-40% Less Than Other Similar Models. This Model And The AngleMix Version Are All Im Going To Be Putting In Unless Some Major Flaw In Quality Becomes Apparent.
