Good build quality as expected from IR. Performance is good, not great. Suitable for daily use as surface preparation. Tool for easy cleaning of sealing surfaces. The exhaust is directed forward and exits to the work surface. This can be a problem when working with coolant and oil that you don't want to spill. Please note that many other models have an exhaust that comes out the back of the tool. The safety mechanism is long and bulky in tight spaces so I removed it and was happy.
