Few would argue that GoPro is the king of the action camera world. It's the brand of choice for professional film crews and amateur enthusiasts alike and dominates the competition in terms of market share and brand recognition. GoPro's current flagship model, the HERO4 Black, is touted by many as the best action cam on the market.

A couple of weeks ago, GeekBuying.com asked if I would be interested in reviewing a new GoPro competitor, the YI 4K Action Camera. They claim that it matches or beats the GoPro HERO4 Black in almost every way for just a little more than half the price ($250 vs $449). I was pretty skeptical of this claim, but after reading a few reviews, checking out the specs, and watching some comparison videos online, I have to say, the camera looks pretty legit.

Here are a few of the more notable features the YI 4k sports:

  • Records 4K/30fps (60mbps), 1080p/120fps, 720p/240fps video and 12MP photos
  • 155° wide-angle lens with F2.8 aperture
  • Built-in 2.19" 640 x 360 LCD touchscreen protected by Gorilla Glass
  • Ambarella A9SE75 Chip and Sony IMX377 Image Sensor
  • Electronic Image Stabilization (EIS)
  • Rechargeable 1400mAh battery with 120 minutes of recording on a single charge
  • 5GHz/2.4GHz Wi-Fi support for wireless remote control
  • YI Action App for instant photo and video editing.

That's a pretty impressive list. On paper, this little guy is looking sure looks compelling.

The camera came in the mail a couple of days ago, but I'm still waiting for some of the accessories to arrive before I jump into a full review. For now, I just wanted to share a few pictures of the hardware and give you guys the chance to help shape my review.

I haven't written about an action camera for Android Police before and I'd love your input on what you'd like to see in the article. I plan on testing video quality, battery life, and the YI Android application, but how I do so is partly for you guys to decide. So tell me, what tests would you like me to perform? I'll be borrowing a GoPro HERO4 Black to use as a comparison, so keep that in mind as you make your requests.

If you'd like to read more about the Yi 4k Action Cam, you can check it out at GeekBuying.com, whom I'd also like to thank for sending out a review unit. Expect a full review that puts this camera's lofty claims to the test in the next few weeks. For now, please leave your suggestions for the review in the comments below.
