So far so good. I did allow the thing to rest for a little over 24 hours to allow the refrigerant to settle. I did not do any water 'purge' of the system, I just put in local (Florida) bottled water and turned it on.
It makes a few 'almost' frozen ice things (cylindrical with a hole) in about 15 minutes from start; they really useful, but in about an hour the tray is partially filled with frosty ice things. Once it gets going a fair number of ice things are produced.
I live in Florida so mine is filled (I think a little over a liter of water about 9 am and produces medium ice things until 10 pm on the single fill, sufficient one to three people with ice drinks throughout the day. I don't have a decent ice bucket, so I can't comment on the 28 pounds per day. Just using the internal tray is sufficient for me.
Be aware that this is a little refrigerator, the fan needs adequate space to blow the heat from the condenser coil and it is very, very warm

Sadly it died in March 2017 after daily use since I bought it. No more easy ice for me. So I guess I got a year + from it. It worked well up until that sad day. Now I'll look around and see what is on the market.

. Also, the ice things (Don't call them cubes) are a frosted color indicating the unit has not taken water to very far below freezing levels. They are fine for cooling water (or other liquids) in glass.  If it keeps going it is a solid 4 stars.
