Plugged this into my Gear 360 camera, which handles 128 sandisk with no issues, this one shuts off after one minute, says the card is full and is buggy as hell- I would not order anything from this company, this is obviously a generic card with less than 2 megs of real space. I trusted their feedback ratings but got screwed. For 3.00 more I could have bought a sandisk and not had any issues, really upset.

Ex Output:
negative

Ex Input:
I was immediately disappointed with the quality of this ring. It bent as I was removing the tag. It's pretty and it hasn't turned my finger green YET, but overall disappointing.

Ex Output:
negative

This is te 2nd UFO drone I've purchased. This model is better than the one I purchased previously from another seller. It holds up better and flies longer. I'd purchase again

Ex Output:
positive
