Product review (4 stars): Portable Ice Maker that meets the RV needs.
Before taking on my RV I ran it at home.  Filled the reservoir about 3 times in about 4 hours.  It took a while to get going but once it did it the machine seemed to produce about (and I'm guessing) about one 5 lb. bag in that amount of time and you have to keep emptying the basket and putting the ice in the freezer or it sill just melt back down into the reservoir and recycle.
I'll be taking it on our next RV trip with the intent to eliminate daily trips to pick up ice.  In my case this little ice maker will pay for itself in about 40 days in the RV.  Bottom line:  not a big producer of ice but it does meet my needs and is well worth the cost.
