Product review (5 stars): GREAT product
Pro: keeps chugging along after two years of HARD service.
Con: ice is a bit soft, but that's true for all portables

We've had this product on the back of our boat for 2 years.  It has a canopy over it, but still gets rained on regularly.  I know it's just for indoor use, but it's been great for years now in fairly harsh conditions with the wet and extreme heat
