This frustrating problem is now solved by using Talking Food Cans which uses a recordable voice message to tell you what the item is. The product comes in the form of a magnetic yellow cap that sits on top of any sized steel can. The cap allows you to record a short voice message, which can then be played back at any time with the touch of a button. It is very easy to use and the voice messages can be re recorded over and over making the product reusable time and time again. The cap is not just limited to canned food. Using special adapters, the cap can be attached to many other objects that are hard to identify, such as bottles, household sprays and plastic storage containers. Uses 4 AG13 batteries.
