This is a tool from Amazon made by Dovaman. The safety switch on the trigger was so badly placed and designed that it was useless for getting into very tight spots. Since I bought it to make straight cuts in tight spots on the boat I considered returning it. Some of the screws were inaccessible without taking the whole thing apart so that is what it took to remove the safety switch entirely. Works fine now. Cheap but maybe I should have bought the DeWalt.
