The fit-and-finish on the S-315 is quite good. The fastening nuts are pre-welded on, which makes assembly much easier. The bolts line up nearly perfectly and no cross-threading issues were experienced. The assembly instructions are very clear and some of the best I have ever seen from any foreign or domestic company. The grill heats up to most cooking temperatures in less than 10 minutes. The only problem I've encountered so far is low gas feed after the second or third use. I removed the hose to the propane tank, tapped on the regulator, and re-attached the hose. The burners then heated as they should. Possibly this trick should be added to the instructions or troubleshooting. The fuel-level indicator for the propane tank is a nice feature.
