Sorry I didn't get back to everyone on this. I somehow over looked it. Everone should have a pump that ordered one. We only have 4 more in stock at this time at it will be a couple of weeks before we see more 6025's in stock. If you have an order for the 45's please contact us through email and I will give you an update. The 55's should be arriving in Jan.
I'm not aware of any problems. No complaints on the 50 pumps we have sold. There is a 1-2 day break in period. During that time they are sometimes a little noisy.
Contact me directly if you are still interested. The site is still not notifying me when someone posts in our forum. Sorry for the slow reply. You can see we are very fast on other forums...
