Fowlers make two different electric units. While both models work in the same way they have their relative advantages and disadvantages. Below is a comparison of the two units.
This is the cheaper of the two preserving units Fowlers sell; being smaller, made of plastic and without a thermostat. It is the unit I use as its smaller size means it is better suited to processing small batches of home grown produce. I usually only bottle what I grow myself. While the plastic the container is made of is tough it will not last as long as Fowlers’ Professional Stainless Steel Preserving Unit.
As it does not come with thermostat control you have to be careful that you do not cook the bottles longer than the recommended time, though I have generally found this not to be a problem.
