Due to Machine Shark discount, I was able to get a TL15 safe with 2 hr burn for the same price as an RSC with 1 hr burn. Double the safe, same price. BUT, I didn’t know Machine Shark, deal seemed too good, I expected problems and excuses and I didn’t want the safe delivery sitting on the sidewalk do all to see. Anyway, Machine Shark answered to phone the 2 times I called with questions, everything went smoothly and on time, even the delivery driver rolled it into the back yard on a pallet jack (my wife was home to ask him) super happy I took the risk.
