This machine worked very well.  The first batch that I tried to make didn't form ice cream.  I suspected that I had not made the custard correctly.  I took the same batch and re-heated it until the custard formed and cooled it as instructed.  Then put it into the ice cream maker and it worked great!  The result was an ice cream that my wife loved.  I then made a second different recipe with no problems.  I will continue to use it.
