Yep, I have no problems with the FX-888D. If I were designing it, I'd add some legends to the control panel, I took the liberty of adding them myself. 
My only gripe is trying to do too much with two buttons. However, once I addressed this simply oversight, I've been nothing but pleased with my purchase.
You have a very handy calibration capability, but if you make a mistake and press the wrong button to enter the tip temperature setting mode, you end up screwing up the calibration. Fortunately, I have the tip calibrator, so I could bring it back into calibration.
I love the idea that I can actually calibrate the tip temperature to the true tip temperature and not a guess like many soldering stations. There's a reason that the FX-888D is used in countless industrial settings, it's a solid and reliable workstation.
