Well done Doyle's for importing this product into Australia! We are a 3 Biothermored household! We nearly have the whole body covered ... But not quite! I first got the large one for a recurring back problem and was hooked ... I then felt I had to get the neck/shoulder unit & it went from there! If I feel any early muscular problems the Biothermored can usually melt them away. It is a really great product - Soooo much better than the old wheat bags(I don't know how many of those I nearly burnt in the microwave!!!). Tip - 30 mins of Biothermored with a glass of wine is a great way to relax!
