||I've been using this for about three months and I'm quite happy with it. It does what it's advertised for, taking smooth videos while moving. The extra battery is something necessary if you want a whole day of filming and the Osmo Base is actually more important than it seems.
People who don't have the base are going to have the most difficult time trying to put their phone on the Osmo Mobile properly. It cannot stand for long on its own and tips over a lot. This is very annoying when you're trying to balance the phone on the Osmo Mobile. You will need the base because there is no hole on the bottom of the Osmo Mobile that will fit onto a tripod. One good thing however about the base, is that there is a screw hole at the bottom which will fit onto any tripod/monopod.
Designed for phones, I'm pretty impressed that its easily adjustable for different smartphone sizes, both for width and length. I used a Samsung S7 Edge and had to take off my protective cover because it wouldn't fit on the clamp, which doesn't properly hold devices with very thick edges.
There's one knob behind the clamp that let's you adjust it to fit your phone horizontally according to its width. There's another knob behind (which is not so easy to access with your hands, you have to squeeze your fingers in a little) that adjusts how centered your phone is, which is very important so you properly balance your phone before turning it on. For my S7 Edge, I had to adjust the knob almost to the maximum due to it's long-ish form.
The joystick is really great, it feels good and has a very smooth touch. It's very accurate in reading how fast or slow you're moving the joystick and the Osmo Mobile will pan at that exact pace.
Record and Photo Buttons
Without having to touch your phone, you can use your thumb while holding the Osmo Mobile to start recording or take photos/selfies ONLY IF you are using the DJI app to make the recording. These two buttons don't work if you're using your in-phone camera app. On my S7 Edge, I have no problems using the DJI app to record, but it doesn't support 4k recording, or recording in Fulll HD (1920X1080) at 60 frames per second that I can do on my in-phone camera app.
Stabilisation (General - without walking)
The Osmo Mobile is amazing when it comes to stabilising my hand movements. Taking general video from a short distance, it really works well to eliminate the effects of hand shaking or awkward movement. I was filming while sitting on the back of a 4x4 truck on a wet, muddy road but my video was ridiculously smooth despite the very rough ride. However, if you're trying to film straight and static at an object up close, tired hands may cause some slight 'up and down' movement, but nothing too disruptive.
The Osmo Mobile eliminates all left and right shake when I'm walking, so there are no awkward shakes when turning and so on. What you need to be careful with are your actual steps going forward. DJI recommends walking by taking steps heel first and properly ending with the tip of your foot to minimise up and down movement. This is because footage can have that video game first person shooter effect of 'up and down' because of your shoulders if your foot steps aren't smooth.
Using it while turning it off and on intermittently, I ran out of battery in about 3 hours. So if you plan to take a day's worth of footage, let's say on holiday or something, it's worth having at least one spare battery. However, its worth saying that your phone battery will probably run out faster than the Osmo Mobile if you're recording on Full HD or 4k.
The Osmo Mobile comes with a short sling bag, but its sometimes hard to fit the Osmo Mobile in because of its large head, you'll have to really fit it in properly before you can zip it up.
All in all, it's a very good product and its very mobile. It does what it's supposed to do. With more accessories, you can even set up a mic, but it's all up to the individual.
