They are all going to fail! Just a matter of when... less than a year is probably not reasonable. But without doing a failure analysis it is just another bad pump.

I like the idea of the Meziere's just for the flow rate and low stress I would be putting on it in my use. It should make it last well, all things being equal. It would also flow more if I wanted to go with the NW/Woody super cooler. (which I am not inclined to do at this point).

As the saying goes.... you pays your money and you takes your chances..
