I got this tool because I LOVE the laser level and it works so well - NOT so with the laser tape! I guess we need a little bit more technology before something like this can be very useful as a household tool. When its low on battery especially, it gives wacky numbers that are nothing close to the actual distance! It also doesn't work well if you have patterned wallpaper - it needs a solid surface! When it does work, it only measures to the closest inch - anyone who has done home repairs knows that isn't nearly close enough! An inch might as well be a mile! I don't recommend this product.
