Product review (3 stars): These Machines Have Their Weaknesses
This is the second ice-maker (two different brands) we've purchased.

The first machine we tried (another brand) stopped making ice after about 10 months. A local repair shop told us the sensor was defective and needed to be replaced. Since the cost wasn't prohibitive, we went ahead and had it repaired. So far, it's working as it should (only been a couple of months).

In the meantime, we decided to buy a second machine to use in our motorhome. We chose the Della based on the reviews. Unfortunately, we've run into problems with it as well. This time, rather than no ice, we get too much ice! Translation: the machine doesn't always shut off when the ice bin is full.

We contacted the seller and, to our surprise, they responded almost immediately. At first, they offered to send a replacement, without the need of shipping the defective one back. We agreed but the seller never got back to us with details. When we followed up, the seller changed the terms and offered to refund our money if we shipped the defective one back. When we inquired about the original offer, they never responded.

At this point, we are continuing to use the Della in our home -- even though it continues to intermittently overfill the ice bin.

From our experiences, it seems the machine sensor eyes tend to be extremely, well, sensitive. (What can you expect? They're made in China.) So if you're thinking about buying one, don't be surprised if it only works for a limited amount of time.

UPDATE: We did not use this ice-maker during the winter. When we turned it back on this month (May), it no longer will make ice and keeps saying there's no water, yet water is to the fill line. IMO, anyone who is considering this particular model, I say Buyer Beware.
