These machines are worthless. We had an older machine we use for about three years when we brought two more smaller ones from premier. We have work with a technician at Lex-Tex since we bought them. They have other customers having same problems we are and now say it the computer board which they can’t get from China. We have lost lambs due to these issues and money in nibbles as lambs chew them off when they run out of milk. The amount of money lost is probably more than the cost of the machines. We are done with this company and plan to either negotiate a settlement or take to court. The ball will be in their court.
