Before this second rusting incident happened, I was really disappointed in the lack of consistency. The first mp40qd I bought was FLAWLESS. Dead quiet and worked great. Liked it so much I bought a second one and that's when the problem started.
They sent a new wetside and it was louder than the first one. Sent out a another one and the unit was still loud. They sent a new dryside and it squeaked like crazy. Sent that back and they sent another one. Finally it was almost as quiet as my first one. Then the rusting happened and they send another wetside. Lol.
To ecotechs credit they have replaced anything right away with no issues, but come on. 5 returns to get a second unit that's as quiet as the first??? Kind of ridiculous.
