Could use some help from my friends. Apparently thereās a Mr Heater in my near future and with the cost of 1lb propane cylinders living north of $5.00 a piece, Iād really like the ability to refill them myself. My cost to refill a 20 pound bottle is around $12.50 so that would mean I can refill these little suckers for $0.63 eachā¦ā¦.big savings. My question(s) is if anyone has experience refilling their own 1lb bottles? Also, what adapter did you go with?? Hereās a pic of the heater just cuz and a picture of the adapter Iām considering buying from Amazon. Theyāre asking $24.99 and it has a 4.4 star rating out of 250 customers which is the best I can find. Thanks for your input.
