Has anyone had a problem with capacitors on RB750, I see that a while back there were problems on the 450, but I don’t see anything on the 750.
From the style you wrote it seems like you want problems with capacitors 
I currently have at least five RB750’s running just fine. In fact, I have never experienced any capacitor-related problems with MikroTik hardware. Looks like they don’t contribute to that 21st century technology plaque. Time will tell though.
No offense btw.
