Okay, Okay.....Here's my 2 cents....
We've had a portable ice maker for 2 years now.....have had issues with one manufactor.....having nothing to do with what kind of water used, but with the coolant.....but now all is well....ours, we've bought online and have cost us about $250...but they can produce up to 35 pounds of ice in a 24 hour period......we have water filter on the water line into the 5er, so mainly use that water, but have used bottled spring water, too.....have cleaned our out like you would your coffee pot....yes, you'll get vinegar "ice cubes"....but after running a second gal. of water thru...the ice tastes fine.....continuious use like we do (that baby runs at least 6 hours here everyday. Got to keep Ernie's beer cold...
).....you will be replacing the ice maker about every 2 to 3 years....we just got our new one........wouldn't be without one.....worth every penny....and yes, if you want to use the ice for an ice cooler, you need to "harden it up" so it doesn't melt as fast, by bagging it and putting it in the freezer.....hope this helps....
BTW, our new is is Retro Red in color....
