I love these. They don't last as long as the gopro batteries but they DO fit in the Gopro Hero 4 silver and I CAN charge all 3 at one time, unlike what other people were saying. I bought these as back ups, definitely a good buy!

Worked perfectly. I used it to connect my GoPro Hero2 to a flexible mini tripod. this is a very useful accessory if you already have a lot of camera equipment that you want to use with your gopro

If you are the kind of person who likes to take a lot of pictures and record a lot of videos like me and does not like to be synching very often, go for a bigger card, if not this one will do its job. I have used it a lot and I have done a lot of synching too.  Works perfect with my Silver Gopro 4. It brings the SD adapter so you can sync or see your pics and videos either on your PC or TV, of course if  the electronic equipments I mentioned have this feature. Quality its good and I recommend this product.

I purchased it for my GoPro4 Silver and it works great, and it's a little cheaper than the SanDisk's or the Lexar's that are the "official" GoPro brands. 90Mb read and 45 Write, hard to beat

Purchased for use in my GoPro Hero 4 Black Edition. Works perfectly. Fast enough to handle higher frame rates or 4K footage! Great card for a good price.

I bought this to use with my GoPro hero 4 silver. I've tried multiple long USB cables that have all failed but using this in conjunction with the original GoPro cable it works perfectly for charging and data transfer.

Seems high quality and sturdy

Works better and is cheaper and easier to operate than my Hero 3. Warning:  Does NOT fit the same batteries as the Hero 3, so it's going to need it's own set of batteries, but it  IS compatible with the  VVHOOY 2PCS 1350mAh Rechargeable Action Camera batteries, which I recommend.  I get an easy three-plus hours record time on a 64 gig card and battery at full quality.  Monitor is built-in and the unit is thinner than a go-pro but otherwise works with all the go-pro type accessories just fine.

works well. The connector is great for the new Yuneec 4K as the power port for the camera is no longer used. Instead, it now has a slide-on contact point.

I plugged this microphone into a GoPro hero 4 silver and get nothing but interference. I got this to have better sound than the GoPro mic but it sounds like crap. Anyone have any fixes for this before I bash this product and return it??

Works great on Gopro Hero 3 plus silver. If you want to play your Gopro through tv this is what you need.

Real simple to use for Go Pro Hero 4, just load the desired memory card into the gopro device. Connect the USB into the camera and the HDMI into any HDMI port on television and using the on screen select photos or video using the power button on camera. May take a moment to understand controls but within minutes you'll be viewing your most recent adventures with friends and family on the big screen. Some lag may occur depending how old t.v. is and the formatting size of the screen.

My one line review:
No issues with working with a GoPro Hero5, some of the slower cards will throw SD card errors at you.

Bought this for my GoPro 4 Silver. So far it works flawlessly.

Lost GoPro in the ocean, bought this as a replacement, couldn't be happier with the quality. It works with almost all GoPro accessories and is better than the GoPro I first had. Totally worth it, the 4k quality is stunning and awesome to look at. 10/10 satisfied.
