There are two different groups of products that need butane refills:
Products that produce a flame for which any make of refill is suitable like ordinary flint, piezo and battery lighters, barbecues and gas cookers, butane candles, primus stoves, industrial blowtorches.
Heat generated thermal products for which only the products made by us are considered suitable, for example windproof turbo flameless lighters, portable soldering irons, miniature blowtorches, portable smoothing irons, butane thermal jackets, all day hot pizza containers, crème brûlée caramelisers, cordless hair stylers and curlers, heat-sterilized cutters for horticultural purposes (vegetables, fruit and flowers), medical, dentistry and veterinary purposes.
