Well I've been using the Sky Viper V2900PRO for a few weeks now and I have to say it's a great little drone. It was a slow learning curve at first as the company didn't include many instructions (for a $200+ drone, real guys?!). But they obviously listened to customer feedback as the latest firmware update provided a detailed explanation. Controller functions and what not. There are still a few small things that need to be changed, but I hope the company listens to customers like me. 1. The automatic hover does not maintain a constant altitude, it always falls slowly, so the user needs to add a little throttle to keep it at the same level. 2. The photos and videos are decent (especially for the price) and some actually come out very sharp, but sometimes the images just look a bit washed out. (enclosed a few examples)3. The app could use a bit of work, but it's been improved since I've had the drone, so I'm optimistic again.4. Back in the app - you have to export the images to the app and then to your phone (double export to get them on your phone) which is a bit of a hassle. But literally everything else was great: 1. The battery life is way better than other drones I've had (even though they were smaller)2. The controllers are responsive and sensitive, but not overly sensitive.3. Just as easy to fly as any other drone I've owned.4. Comes with an 8GB memory card if you don't have one, but it works great with my 32GB Sandisk Micro SD5. Propellers are easy to install/replace - they bolt on to make them more secure and come with a tool to hold the motor when unbolted. It's a good weight so it doesn't get blown away too much by the wind, but at the same time it's compact enough to travel with. Start FPV flying, photography, etc. without going broke.
