Useful and most of the time no problems!
I found this application really useful and only had a few problems with it unable to find the product that I want. It is accurate and found everything I scanned correct. It was difficult to use at first because I was holding up the item and it had problem scanning. When I placed it on the floor I didnt have any problems. It wasnt able to find some stuff though, such as some stuff that I purchased in a dollar store or something similar to that.
