Yes, we are getting a little fed up with this situation. We order way over 95% of our repair parts from them and this is disrupting our normal workflow tremendously. It is hard to believe that you would not have some contingency plans in place if you were as large as PartsSource.
I frequently order from PartsSource, however it is still down. I started ordering dialysis and RO parts from svsdialysis , they ship fast and prices are reasonable.
