Query: can't say i am impressed with it but it works (more or less)

Need to reset every now and then, accuracy is +/- 1;2 ft. So i can not say it does not work because it does and trying to do best but i would not rely on accuracy of the tool. Also cant really use it outside on sunny day. Because it wont see reflection of the laser to calculate the distance.
