Mobile World Congress 2015 showcased many smartphones, tablets and wearables, but some of the most interesting aren't big name flagship devices.

Smart suitcase

It's fair to say the Smart Suitcase is humblebragging about its functionalities. Using its app, it can weigh itself --so you never have to worry about paying extra at the ticket counter. You can also use the app to track it if it gets lost.

High-tech dog collar

Pet tech is by far the cutest category of gadgets. We first saw the Motorola Scout 5000 earlier this year at CES 2015, but we had to wait until MWC 2015 to get our hands on one. Check out its cool streaming abilities above.
