I did not practice much with it before the trip, but the video clips turned out great. Highly recommend DJI Osmo Mobile for those would want to use their mobile phone as camera & want a steady shooting for the mobile video.
Here's the official website : http://www.dji.com/ but I got it from http://www.march.my/ (Malaysia online store selling DJI products). You can also get it from tech stores in Kuala Lumpur. I've found it in Pavilion (camera shop) and Midvalley. Do compare the price if you want cheaper.
