Seems they will work well for me, because i can get an import beer here from Belgium, which is good beer anyway, and then after i have guzzled down 2 cases or so (20 bottles in a case), and sterilized them, then i can easily bottle mead or cider without having to buy or replace any bottles... and from the prices i have seen online, i am paying much much less doing it this way than i would buying new swing top bottles. This is important for me here, because getting new bottles and caps/ capper/ corks, etc... has proven nearly impossible.
Support Medicinal Mead
Another reason not to boil honey when making mead: Honey which comes from local bees carries pollen and pathogens relevant to your area. Consuming these natural medicines will boost your resistance to local pollens and other allergens. Boiling destroys them.
If all else fails, just drink more mead anyway...
