"I've been a customer at SJ Smith in Decatur for 10 years now, and every time I stop by, the guys there are so incredibly friendly and helpful. From refilling my oxy/propane mini tanks for metalsmithing work to swapping out my propane tank on my grill, they've always helped me with everything I've needed. When I first started out with a torch, one of the guys even helped me figure out how to disassemble and reassemble my torch and gauges to my tanks safely. Its always a pleasure to swing by."
