Haven't had the opportunity to use my Superguage XL as yet, however bought it to have when remodel takes place in the near future. That is why a four star rating. My biggest concern isn't the tool itself but the cost when compared to a similar product I saw after it finally arrived, sold at Menards for half the price. My next concern was shipping. This product came directly from mainland communist China, and took almost a month to arrive. I wouldn't waste my time or money ordering anything ...
