There should be ranking for quality of products,just like the one on
energy efficiency so when we buy products we can be sure they will last without problems on things which are manufacturer defects. Example would be iron pipe which goes under plastic in freezer where the door closes.It makes opening easier but it is also most common problem which makes fridges lose gas. Second would be making fridge compressor stronger so they can take workload when it is hot since they are weak for hot climate
