Low frost (or lowfrost) vs no frost integrated freezers

[Adsibob]

Last time I bought an integrated freezer, the choice in terms of frost technology was:

• a normal freezer which would build up ice/frost and so require defrosting at least once a year;
• a clever "frost free" technology that meant you didn't have to bother with this.

 

There now appears to be at least one more type of tech called "lowfrost". Siemens and Bosch seem to suggest that their lowfrost freezers have internal cooling elements within the cabinet sides and back which have much less ice build up.

 

Does anybody have experience with these lowfrost integrated freezers? Are you happy with it? How often does it need defrosting?
