Summary: I have mounted this camera on the handle bars of my Four Wheeler, On my Helmet while I Snow Board And on the Gun Barrel while I play Paintball. It's very tough, easy to use and Fun to make movies with. The video can be a little Jumpy in Rough activitys and the audio Is ABSOLUTLY worthless in EVERY situation because of the waterproof seal over the mic. For the money this is a perfect tool for beating the snot out of electronic gear and sill getting a mid level video.
Summary: I looked at a several types of these helmet cams online. This seems to be a pretty good one for the price. I purchased it as a gift for a dirt bike rider. He used it in an hour and a half race and was pretty happy with the quality of the video, although he had to duct take it on to his helmet. The straps that come with it wouldn't keep it steady enough. He turned it on for a second race and it stopped after just a few minutes.
Summary: I've only had the item for 2 days now, and I would agree with some of the other reviews about poor low light capabilities. But what do you expect from a cheap camera? If you want something better and have a lot of $$$, then go for the vHoldr camera or better. Video quality is comparable to what you see on Police videos. Pros: - Price (less than half of vHoldr) - AA batteries vs. built in or lithium - Cover on the back is easy to remove and replace.
Summary: This camera has absolutley horrible audio quality, however, this is not a big issue as I only need the video. It works best outside on bright days, for instance snowboarding, or riding a motorcycle. I attached it to my snorkeling mask and it was pretty effective. The video quality is a little better than a cellphones. Worth it if you do crazy stuff and are likely to break a nicer camera.
Summary: I mounted this camera both on my helmet and my mountain bike and took it on some singletrack adventures. I had several wipeouts where I landed on the camera or the camera directly hit the ground, and it continues to work great! Since it is waterproof as well as shock-resistant, there are no microphone openings, which means that the sound quality is very poor. I just disabled the audio.
Summary: I'm very pleased with the accessories which come with this cam. the quality of the images are on a good base, sound is not really fine, but it's a action cam, not a digital mic. overall i'm happy with it, reasonable price for this item.
Summary: The ATC 3K takes video about the same quality as a high-end cell phone but the sound is garbled, whiny and non-usable. There must be some kind of membrane protecting the microphone in order to work under water and I assume that is the reason for the terrible sound. It is well worth the money and I am happy I bought it but I wouldn't recommend it for important videos--only "just-for-fun" videos.
Summary: I bought this primarily to be used as a car dash camera. I attached the helmet mounting bracket to my dashboard and record my commute to and from work each day. The video is as good as you would see on cops or other police video shows, actually better than some. There are only 3 buttons for the user interface, on/off, camera, and menu. The menu options I still haven't figured out. But for the most part, you turn it on, start/stop the video, and that's it.
