Eggbeaters - what mileage before service/replacement?

Trojan

Fellow Eggbeater users, what kind of mileage are you getting out of your Eggbeaters before you need to service or replace them?

(Anyone using them on the road?)

Have them on all my bikes, Can't really put a number on how often they need serviced, but you can feel it in the way they turn, and if they are well and truly neglected they get a bit of play in if you twist them the way you would twist your foot when you're clipping out. Super easy to do it, I find myself popping them off and regreasing the bearings whenever i've nothing to do. Seems to be the key to longevity, especially in the kind of environment they'd be exposed to on a mountain bike. I had to replace the bearings in my first ones, probably due to neglect,but they were super cheap on ebay, and with servicing every few months they're still going strong. There is a load of youtube videos on how to do a teardown on youtube too

I've the candys on my hybrid, which is basically a flat barred road bike, and i've never even touched them. Got them incase I wanted to cycle in flat shoes on them, which is still impossible, it is like cycling with a lego piece in my shoe! Not too sure why they aren't on road bikes, my guess is because they've the 2 hole SPD type cleats and not the 3 hole ones you'd find on road shoes?

I was wondering because I've brought a few of them to failure now. One caught in time, the other two failed on a spin which was awkward, but thankfully no crashes.

In fairness, all of them had significant mileage and zero servicing, but for the wallet's sake I think I need to start doing service rather than replacing them every time
