SanDisk makes a lot of claims about this card and some of them are questionable. I own two, and while the high-capacity/low-price certainly makes them useful, they're not the answer to all of my recording needs. First of all, do not use this with a GoPro Hero 3 (or later model). Despite SanDisk's claims, these cards cannot handle the demands of true HD recording. GoPro removed it from their list of recommended cards because it caused the cameras to lock up and turn off. Even with myCanon VIXIA HF10 Flash Memory High Definition Camcorder--technology which is over 10 years old--the SanDisk Ultra card does not meet the requirements for shooting in FXP mode (1920x1080, 17Mbps) even though the camera says only a class 4 is required. A firmware update to the GoPro 'fixed' the issue for Hero 3 and Hero 3+ cameras, but it did so by throttling the recording speed for the cards, i.e. lowering the quality of the recording slightly.Those shortcomings aside, the SanDisk Ultra can shoot in XP+ mode (1440 x 1080) on the Vixia HF10 and it works with all of the settings of aContourROAM Waterproof HD 1080P. Is it "water-proof, temperature proof, X-ray proof, shock proof"? I can't say. The ContourROAM is a waterproof camera, so even non-waterproof cards are safe for submersion if they're in the housing. The Ultra has functioned in 10 weather and after being dropped, so there's validity to the claim of it being temperature- and shock-proof. I guess I'll find out whether it's x-ray-proof the next time I go through the airport...
