The gyres are the single biggest piece of crap equipment I've ever purchased in the 17 years I've been in the hobby. Went through 6 in 1 year. I know some of the service techs around town hate them and have had the same issues that I had with them.
That said, the flow on them is amazing, nothing in the hobby is even remotely like them. Too bad they are junk.
I ended up with 4 of the MPQD60's and haven't looked back.
