Tried two of these in my Nikon D3200... They kept freezing my camera!

According to the card stats this has what my camera needs for HD recording etc. When I was taking photos at my 3 year olds birthday the camera kept freezing up and because of it I missed a lot of pictures. My interim card I had been using did not do this. I ordered a second and the same thing happened. I finally gave up on this and bought a Lexar with similar stats and have had ZERO issues.
My online research said that the cards that were fake caused these sort of issues. I would not buy this again, I was able to return both.

I only owned this camera for two days when it froze up on me TWICE!  When it freezes up you can't turn it off or anything, you have to take the battery out to get it working again. Also the Easyshare feature is lame as you still have to hook the camera up to a computer for your picture to be loaded, so what's the point?!?!

Also purchased a NEW Kodak SD card,(the same one pictured on the box!), that wouldn't work with the camera!?!? It kept giving me an error message say it was incompatible, did I mention that it was the same exact one that was on the cover of the box?  Anyway, I got frustrated and put the card in my mother's camera to see if it would work in her camera and I got this nice little message that said:  "Card needs formatting", I clicked "ok", then her camera formatted the SD card!! When I transferred the card into this camera it now worked, so why the hell didn't it just format the f$*ing card instead of telling me it was incompatible!?!? Piece of crap, you're going back!!

The camera has been freezing on me miduse, the footage I have from it is great, no complaints there, but i just don't understand what the issue is with it. It will completely freeze as I'm trying to work it. this forces me to take it out of the case and take the battery out in order to restart it. It has not been very reliable for on the go recording.

I bought this camera for a "once in a lifetime" trip with a friend,  shot about 10 test shots before going on the trip, there it the lens locked up and showed an error "turn off and on again"; I couldn't believe this had happened with a Nikon camera, had to use my friends camera to take pictures at a much lower quality.  Returned the first camera, and thinking it must have been a 1 in a million issue, got a replacement (same model)... 2 shots in, the same issue.  I'm done with this model.  There are reports online of this issue and hints at firmware update to prevent it, but if the camera is locked I can't do that either.

After reading all the good reviews, I thought this would be a great camera.  I did read some reviews where some people mentioned the lens getting stuck on their cameras, but since the good reviews outweighed the bad, I thought the odds of that happening to me were pretty slim.  Well, the odds were against me and now I have a camera with a "lens error."  I've tried everything to my knowledge to try to get it to work again and nothing has worked.  So, I'm sending it back.  Thankfully, I got most, if not all my pictures off of it before this error occurred - at least I hope I did.  Since the camera won't even turn on now, I have no way to tell for sure.  I thought Nikon was much better than this - it's a simple point and shoot camera - how can they mess that up?  Now, to look for a new camera ..... again.

I had a generic backup that I didn't know wasn't holding charge until I got to a wedding. Luckily I limped along all day on the one I had (D7000 is pretty great on battery use). I'll never buy a generic one again. Stick with Nikon. Thanks!!!!

After owning all the GoPro cameras, I am Very sad to report that this camera (Hero3 Black) is an absolute NO BUY !  Even with the so-called Fix of Firmware version 2.37 in April 2013, the camera freezes up so much
that it's sure to completely Ruin any vacation or that priceless shot you Thought you were getting! I have tried every possible fix to include: Replace battery, try 3 different class 10 (ultra) 16G cards, Manual load of firmware 3 times, Protune off/on, etc.  The WiFi remote works well until the camera freezes, then your back to removing the battery again. Battery life is poor at best. Bad camera??- I think not, it's my second one. Great idea but overall a useless camera compared to the Sony or Contour.

UPDATE 04/28/13:  GoPro RMA'ed and sent me a replacement camera under their One Year Warranty Policy. In calling Customer Service, I explained what I had tried: Reset camera, Replaced battery, tried 3 different class 10  16GB  Scandisk Ultra cards, Reformatted all with camera many times, installed Manually- Firmware V2.37 Three times, removed battery and reset= with No help and camera freezes consistently .  So they felt it was a faulty camera ( which was one of the First shipped on New Release of the Black).  With New camera and now using ScanDisk Extreem Pro 16GB Card I have tested ALL modes i.e. 1080p @ 60FPS, Protune. Time Lapse etc.  With Numerous Tests I am unable to duplicate any previous Freeze or WiFi problems, and the camera is working perfect. It is only my suspicion , that the Hero3 Black requires even better than a ScanDisk "Ultra", and that the Extreme Pro Card appears to be the way to go.

Add another E18 error code complaint to the list!  I purchased the camera about a year ago, and have had the E18 error for about the last 2 months.  The camera will intermitently freeze up and not work at all, just beep at you and give you an error code E18.  I've tried all the recommended fixes from the compressed air to the alignment twist.  Nothing seems to keep it functioning for more than a few shots.  Canon wants nothing to do with the fix, and estimates repairs between $150 and $200.  Save the headaches, and buy another camera from a different manufacturer!

One moment it works fine, you turn it off, then on again a few minutes later only to find out that it would not power up again. It is an  experience to remember from your European vacation! After reading the reviews above I realize that I am not the only user experiencing the problem which suggests a faulty design. Nikon might have identified it as such when they admit in their description of the firmware upgrade v1.1 that it fixes (quote) "An issue that, in some rare cases, prevented the camera from turning on, or prevented operation, has been resolved". Unfortunately, when the camera does not power up one cannot install the upgrade by himself. I was advised to send it to the Nikon service shop where they would fix my camera for estimated $109.50 + shipping. No surprise that the camera ended up in the recycling bin after about a year since purchase with a vow to never touch a Nikon again.

I bought this for my new digital camera. I tried both cards in the camera and one of them failed With in minutes of test shots.  I kept getting "memory not detected". It may be one in thousands or hundreds of failure,  But I decided to return it. Amazon wax good at refunding my money.

In two separate cameras (both Nikons), on two separate cards, I've had data loss. One was recoverable by PhotoRescue, the other not. I'll be happy to post more details if prompted, but I can say I won't be using either of the cards I own anymore.

I ordered this battery for my D3200 over a month ago. I received the package in good shape.  However, the battery would not charge, would not work in the camera.  My other battery charges and works fine.

Today, a month after receiving my refund for returning the battery I receive an email from the company asking to leave feedback. Here it is:

It didn't work.

Not compatible with compact digital cameras. Note: I have a dedicated, threaded adapter that attaches to the camera body's lens accessory lugs. (Canon G) You just remove the small ring and replace it with the threaded adapter. This slide duplicator attached to that adapter perfectly, but the camera wouldn't focus on the slide at any manual focus setting or zoom, or auto focus. Just a consistent blur. I tried all my Canon "G" models, 10, 11, 15 & 1x. Didn't work with any of them. I even tried to see if the tube had to be longer or shorter by moving the camera close to only the end part, and also tried backed away from the tube. Then I decided to try the closeup lens that came with it. Problem is, I couldn't get the lens cap off that thing! I even have a good set of filter wrenches. No way! that thing is really tight. I think somebody glued it on there by mistake. The next step would be 2 pair of Channel Lock pliers (with protective leather wrap), but I didn't go that far. That thing is on it's way back. I'm going to try photographing the projected image.

This is my third Nikon Coolpix AW camera...all have failed similar to other postings.  Fog in lense, then lense failure, now no longer responsive to input keys on back.  It ruins holidays, even if you get your money back with purchase protection...time to move on to another product.

Shot with these, bought 3 of them. Had to replace them because 2 of them showed that there was no memory on the cards after doing a photosession. ON TWO of them... Clearly not user error. I had 3 other photographers try and it happened to them.

Looks decent, works decently, aaaand then it freezes and shuts down when it's too hot in the car??? Horrible purchase. Returned it after few days. Got the replacement, tried that again (in not that crazy-hot summer), and it was freezing all over again. Returned that one too, and didn't want the third replacement.

11/02/2016 - UPDATE - I was approached by ZeroEdge customer support, they were super nice and they offered to send a replacement dashcam. So far so good, the cam is working great, but it's cold outside (November), and I can't properly test how the unit will work in the summer. I'm upping my review from 1-to-3-stars, and if everything keeps working through the summer - I'll bump it back up to 5 stars! Thanks! :)

Purported to work with my Belkin camera but I could not get it to work. Maybe I need to study more!
