The W4 is about 2½ inches long and 1 inch wide weighing in at barely over 1 oz. The camera comes with accessories so you can mount it one of two ways. One way is to use the 360° rotatable clip that can clip to pretty much anything. My preferred way to carry it is to use the adjustable magnetic neck strap. I put the strap around my neck and the small magnetic plate under my shirt or jacket (you can wear it on the outside of your clothes too). Then I just place the W4 on the outside of my shirt and it holds securely to the magnet.
The W4 has a great feature usually only found on more expensive models that allows it to do loop recording. This means when your memory card is full it will continue recording by recording over the oldest previous video. Even with the smaller 64gb memory card you will get ample video space as it will hold a little over 11 hours of video before it needs to overwrite a previous video.
Battery life should suffice for most applications as in my testing the W4 could record video for 2 hours before the battery went dead. Recharging the W4 is done by connecting the camera via USB-C cable to any USB charger. Copying video to your PC is easy by connecting the W4 to your pc via a USB-C cable. Videos files are compatible with most applications since they are the common MP4 format.
The W4 has just one button in the front and is used to turn on the camera and just one press starts and stops recordings. It’s super simple and convenient. The only improvement I would like to see is the single button on the front is flat against the body of the camera and therefore makes it a little difficult to find with my finger. If the button was raised just a bit it would make it easier to feel and be a nice improvement.
My reasoning for buying a body cam is that I have a dash cam in my car in case a “situation” arises, so it seemed like the next logical step would be to use a small body cam when I am out and about in certain circumstances.
Overall, this is a great camera especially for the price and you won’t regret buying one. I have attached a short video of me riding my e-bike so you can see the quality of the video. A body camera by design does not have image stabilization so it is normal to see movement when walking around, etc. If you need an action camera with video stabilization for sport, etc. buy a GoPro, if you want a body camera, The BobLov W4 is the one to buy.
