Query: Not for Professional at all

I do not expect it perfect tool at [money]. The reason I bought is for only rough estimate quickly. It has to aim straight 90 degrees against flat objects to get correct distance. It is not easy to hold like that with a free hand. I have owned another kind of brand for many years that does not have laser targeting. I paid [money] at [my local home-improvement store], but I have never used it at job site because of too many mistakes. I thought after many years they had changed a lot in technology. There is no difference at all between now and many years ago. Only I paid more for I could not use. It looks excellent for vacant places at this price. I had a chance to use high tech distance measuring tool from Hilti. That is very easy to use and accurate. But expensive.
