  • Very simple to use with a single preserving time.
  • Lower failure rate of jar seals due to the water not having to reach boiling point and the tops of the jars sticking out of the water.
  • Easier on the back as the tap on the bottom of the unit means it can be drained of water without having to tip it.
  • Readily available in many hardware stores (Australia)
  • More expensive than stovetop units.
  • As they use electricity they are not as environmentally friendly as a stovetop unit on a gas cooker.
  • Can't really be used in homes that aren't on mains electricity.
  • Longer processing time.

  • Cheaper than electric units.
  • More environmentally friendly as they require less water and can be used on a gas hotplate.
  • Better suited for use in kitchens that are not on mains electricity.
  • Can only be bought second hand,  which means they are not always readily available.
  • More complicated to use as cooking times vary depending on the different jar sizes.
  • Harder on the back as you have to physically lift the unit in order to tip out the water.
  • Higher failure rate of jar seals due to the water  having to reach boiling point and the tops of the jars sit out of the water.
