Gyres - short lifespan?

Hello,
I'm wondering if gyres are just not expected to last, if I bought a dud brand (I have the Icecaps) or if I'm doing something wrong?

I have the icecaps (larger ones, the '400s' I think) two linked on a controller, at either end of my 6ft tank. I clean them in a citric acid bath in a bucket every 3 months. This is the second set I've had on the tank after the first ones just wore out after about 2 years. I've had these about a year now and again I'm seeing the output from them falling dramatically despite my efforts to keep them clean.
I am therefore again looking to replace them and while I like the agitation and wave patterning you can get from a gyre, I don't want to throw more money on the fire if all the brands are as poorly put together as the icecaps seem to be. Are the other brands better? Am I just better served putting large tunzes or sicce pumps in there instead?

Thank you.
 
I run 2 of those on my 40b and probably clean them at most twice a year. Set on sps random from 60-100% intensity.
