The Hiku produces audible cues after it scans a device to inform you whether each scan was successful, but I sometimes had difficulty hearing the high-pitched tones. A quick peek at your phone will provide confirmation. If you inadvertently scan an item more than once, the app will indicate that you need more than one, which might cause confusion if multiple people are doing the shopping. I don't consider either of those issues to be deal-breakers.
In its current form, the Hiku software doesn't have hooks into any online shopping services, so it can't inform you of deals or allow you to order anything line from within the app. The company says those enhancements are on its development roadmap. My wife likes to participate in the shopper loyalty program that our supermarket chain operates, and she said she'd like to have the Hiku tie into it. That way, she could add current sale and promotional items to her Hiku shopping list (although that kinda sounds like impulse buying before you even step foot in the store).
We've been using the Hiku at home for several weeks, and it's working for us so far. It's simple, easy to use, and effective. I like it a lot.
