I use this AI Language Translator Device as a real world tool.We live part time in Mexico, but my Spanish language skills have not caught up to my need to communicate with the locals. Some of the locals whip out there smart phones and use the translation program available online...but it doesn't work when offline. I have a lot of off line occasions where I live...either no signal or no more data available on the cell plan.This Kentfaith translator shines when I am without cell service. After downloading the off line language pack, you can translate without cell service.... It's a little slower, but nothing as slow as me trying to find the words without the translator. I'm also impressed with it's photo translation using advanced OCR image recognition...74 languages online and 40 languages.offline...as long as you have downloaded that language pack. This translator has a built in camera...take a picture of the item to be translated and the screen will display what it interprets.Now it's easier (but not perfect) to "read" printed material like menus and labels, contracts, HOA documents.It has Currency exchange built into it as well...another thing that Gringos get hung up on. I always use to use an app on my phone...but now, since I use this translator more than the phone for language translation, it's very handy to convert currency and face a Hugh surprise at check out!Touch screen works well and is easy to use. Navigation is practical and efficient.Size is the same as a cell phone...fits easily in my pocket.This is like having a friend come downtown with you so that you can understand and interact with the locals.
