Instruct: Classify Amazon reviews into positive or negative sentiment
Query: Just a very bad product, avoid it.

We bought three of these things for Xmas replacement for some older evaporative types types. The first worked about a week out the box, I thought that was a fluke. The second one worked only for the first fill of water before failing. The third is still in the box, but now I see all these recent December reviews that other are having problems too. CAN YOU SPELL CLASS ACTION LAWSUIT. There is enough posting right here to prove a good case of bad product design. We want a refund, not an excuse and we want it from Amazon as the seller. They can deal with maker.Update: All three went back to Amazon, painless and professional. I noticed a ton of new negative reviews have appeared since. Drop this product. We still need replacements, but this maker is not of the list of those we will considering.
