Save the yellow card with technical support information on it just in case you need it (I almost tossed mine not paying attention to what it was). The night vision for me is okay but I use it during the day mostly when I am out, and since I am generally home at night I really don't bother with it much at night anyway. I have had no issues or any need for customer support. Depending on your needs that maybe something you want to do as well. But I was able to just get a longer Micro-usb cord to use with it. The only thing I will note is I would have liked the cord to be just a little longer for my use. I was able to get this going without any help, the instructions provided walked me through the entire set up. I am 39 years old and I am probably the least tech savvy person my age, I often find tech devices intimidating and hate updates and changes to apps and things I use. Easy to use even if you are not tech savvy. You will need to subscribe to cloud service or use a SD card in order to save images. My husband likes the peace of mind that he can also check up on things should he need to be away from my son and I too. I have had no issues with using this camera, it is small and compact but still provides me with clear images. That and also because it works on IOS and android (we are a house divided my husband is die hard android and I prefer my iPhone). We had noticed a few times that things had been moved on our porch, and I had missing deliveries at times. Got this to keep an eye on our home when we are out since we are very rural, even a trip only for grocery shipping takes a few hours.
