... Switches are not sealed well. If you use it to cut upside down (as in cutting a ceiling), dust gets into them. Sometimes the safety cutout switch jams in the "on" position. And once the trigger jammed on -- had to remove the battery to stop the saw. Exciting! Other problems -- LED did not work on the charger that came with mine. Battery was very difficult to remove from saw -- usually solved by opening the case, then rapping on workbench a half-dozen times.
