Product review (5 stars): Wish I had bought it sooner!
After reading the reviews here, we decided to give Mr. Freeze Portable Ice Maker.  We purchased it for $179 at Costco.  We are *so* happy with the purchase.  This ice maker will pay for itself in no time -- no more inconvenient trips to the store for ice, plus we can take it camping and save the hassle (and expense) of filling those 3 big ice chests up for a week.  Mr. Freeze makes ice in 3 different sizes.  It was a little slow making ice at first but once it had made a few trays the ice kept coming faster than I could keep up with emptying it.  Someone wrote a review mentioning the ice has a bad taste and someone else wrote a review saying that the manufacturer said to put in lemon juice or vinegar to get rid of that taste -- both reviews are correct.  The ice did have a bad taste at first so I remember what one reviewer suggested doing (that is, follow the advice of the manufacturer and use lemon juice or vinegar) -- and we have not had a single problem with taste since.  The ice is perfect!  I don't know how we got along without this machine.  It's one of the best purchases I've made and well worth the money.
