Well may have been built on a monday after rough weekend cut one angle turned to cut other did great then when i went to cut other way motor was hot as heck think switch was bad or motor this happens am going to get same kind try again will give update this one is working fine some times something didnt get soldered right in motor it happens but this replacement is working fine happy with it try to use files mostly but comes times chains get to dull this save me time and money the item felt hefty and solid and the craftsmanship was high quality
