Reading the reviews on this machine scared me, but at my age I needed a bottom loader. So, I purchased an extended warranty for three years. (It was worth the $25 for peace of mind.)
Just be sure to buy a late model machine because Richard, the Customer Service rep at the Primo factory told me that, "The older machines have smaller compressors and are subject to failure."
I just hope my good luck continues. It's a real bear re-packing this machine to send back, so save your box. I had to ship back the last machine after one day. (The older model with the defective compressor and the cold water dispenser that wouldn't get cold, was sold to me by another company, not Walmart, as a new machine. Richard at Primo, after I read him the serial number, told me the machine was three years old even though it was factory packaged.)
Remember, with this machine you have four areas of concern, the pump that pulls the water up from the 5 gallon jug, the hot water dispenser, the room temp. water dispenser, and the cold water dispenser.
At this point, we're extremely happy. Everything works. So with this in mind, I'm looking forward to using this great bottom loader for years to come. Be sure to read the instructions before you plug the machine in. Hope this helps you in your buying decision.
