Product review (4 stars): Good thing the surface around the burners is saftey glass
Update 2:  I receive a email and callback as promised by the Customer Service lady who took my information and promised to have someone call me back.  The email stated that Ramblewood would honor their warranty and replace the cooktop.  5 days later I received and installed the new cooktop in the motorhome with no hassles or complaints.

The only reason I don't rank this 5 stars is because the way you have to adjust the burner flame is by using a long shaft jewelers screwdriver inside the burner adjustment stem.  Both the original and replacement cooktops required adjustment.  Note to manufacturer:  please redesign this by placing the adjustment along side the stem or include the screwdriver with the unit.

Update: Called Ramblewood today to see if they will cover this under warranty.

The glass top shattered while boiling water tonight.  Good thing the surface around the burners is safety glass.  Unfortunately the return window expired 2 days ago.  Not happy.
