I don't leave reviews much, and honestly getting the pro version for a review is a great offer.
That being said, pro version wouldn't entice me to leave a good review if it wasn't true. Hopefully anyone reading this will also get the in app offer of reviewing for pro version. I sincerely recommend trying the free version out. I haven't used it much but going through it I have to say I'm impressed.
I'm a bit of a nerd and from my experience finding a video player that does what you want and has features you enjoy can be hard, even on pc. On the iPhone, I've not found one I've actually kept as long as this. It plays the video files I want, looks nice and very well setup, and doesn't mess with the video quality. I haven't even seen all its features or settings yet simply because I've not needed to touch them yet.
So, if you're willing to trust a random guys review in the slightest, try the free version. I think it's worth having and honestly, not sure what all comes with the pro version. Heck if they give me the pro version like the in app offer said I might leave another review after playing with everything pro has to offer. For now, like I said, I haven't used it much or messed with many settings, but that's simply because I've not needed to yet.
