I purchased a Cuddeview X2 because I expected a good product. The problem is the misleading sales pitch, Works with most other trail Cameras. I don't have a Cuddeback Camera. I tried viewing an SD card from a ****** Trail Cam and it would only show a dozen or so pictures before locking up. The only way to clear it was to remove a battery. I contacted support by phone and told them the problem. It was a format problem, which I expected. I got a surprise when I asked them what were the other brands of trail cams that were compatable with the Cuddeview. Their answer was Don't know ? I would have to try an SD card from them to see if it locks up. So having to do that it's very possible that none of the other brands will work, contradicting the claim that it would work with MOSTother brands. It's not possible to check something like this out before you purchase the product.
I have the same problem with my brand new X2. I have two different cameras neither one is a cuddeback. It works with one of them, but not the other. After about 6 pictures it locks up. I'm not impressed with this thing and wish I wouldnt have bought it.
And of course like you, I figured "Cuddeback" so nope, the reciept isn't that important...
Guess I need to find a cuddeback owner that wants to try it..
