Almost everybody who buys a waterproof action camera automatically picks the GoPro. It's understandable since GoPro has the most widely recognized brand name and offers excellent quality. The great news is that there is a very cheap GoPro alternative, the excellent WiMiUS 4K. It comes at a tiny fraction of the GoPro's price but surprisingly offers very similar and sometimes even better features than it's big brand competitor. We tested both cameras independently and highly recommend that you give the WiMiUS 4K a try. It's a great and very fun camera that will save you a LOT of money.
The GoPro HERO4 is the status quo for action cameras. But in the few years since it was first released, new alternatives have emerged. We'd recommend the GoPro HERO4 to people looking for the absolute best slow-motion video performance (see below). So if you're looking to shoot a lot of slow-motion scenes, the GoPro is hard to beat but comes at a price. If slo-mo is not your main focus, then you can save a lot of money by getting the WiMiUS 4K instead.
The WiMiUS 4K is an amazing deal. It offers virtually identical specs and features to GoPro's flagship camera but can be bought at a much, MUCH better price. There's frankly no reason why you shouldn't try the WiMiUS, it's price point makes it almost as affordable as some disposable cameras (!) which is incredible. Best of all it comes with dozens of free accessories the GoPro doesn't include (like two extra batteries, 4 different mounts, and more). It offers great value!
The GoPro HERO4 Black supports 4K UHD video at 30 FPS, 2.7K video at 60FPS, 1080p HD video at up to 120 FPS, and 720P video at up to 240 FPS. The camera offers excellent video quality and produces smooth shots with a slightly wide fish-eye look.
The WiMiUS 4K supports 4K UHD video at 30 FPS, 2.7K video at 30FPS, 1080p HD video at 60 and 30 FPS, and 720P video at up to 120 FPS. It's a close match to the GoPro with slightly lower FPS for 1080p and 720p. In everyday use, differences were not noticeable.
The GoPro HERO4 offers 12MP still photos, surprisingly lower than the WiMiUS. The camera can do quick photo bursts of up to 30 frames per second.
The WiMiUS 4K features 16MP still photos, beating the GoPro. The camera supports photo bursts at 20 frames per second. This is very quick but slightly slower than the GoPro.
The GoPro comes in a rugged case which makes it waterproof up to 131 feet (40m). The same depth as the WiMiUS.
The WiMiUS includes a very similar, high-quality case which makes it waterproof to 131 feet (40m), matching the GoPro.
The GoPro camera offers built-in Wi-Fi and Bluetooth support to connect it to the GoPro app. Both wireless and the app work great and were very easy to use in our tests.
The WiMiUS offers Wi-Fi as well which makes it very simple to connect the camera to the free app. Unlike the GoPro, it doesn't have Bluetooth - but we found Wi-Fi sufficient.
The GoPro offers excellent slow motion features. You can shoot slow-mo at 1080p with 120 frames per second or take it even further at 720p with 240 frames per second. In this category, the GoPro wins over the WiMiUS, offering better slow motion video. If you're primarily buying the camera for this it's a good choice.
The WiMiUS offers slow-mo at 1080p with 60 frames per second and even slower video at 720p with 120 frames per second. Both look great when slowing down detailed scenes, but are not as slow as the GoPro. Personally, we think the slightly better slow-mo video is not worth the large price tag of the GoPro though.
The GoPro supports both time-lapse photos and loop recording. Both are useful features: Time-lapses are fun to document stretched out events like sunrises and car-rides. Loop recording is useful if you plan to use your GoPro as a car dash-cam.
The WiMiUS offers the same time-lapse and loop recording functionality as the GoPro. We're surprised by the addition of these advanced features since the WiMiUS comes at such an affordable price. Either way, they're great to have!
Battery life on the GoPro is about 1 to 1.5 hours of continuous recording. It's relatively short but current action cameras are very processor intensive so it's quite common.
The WiMiUS has a very similar battery life to the GoPro, about 1 to 1.5 hours of continuous video recording and photo shooting. This time is the current standard for most action cameras.
The free GoPro App connects to the camera wirelessly, allowing you to control the GoPro, share videos, and more. It works great and is a lot of fun to use.
WiMiUS offers their own, free app called XDV. Like the GoPro, it works for both smartphones and tablets, and on both iOS and Android.
