    "I would definitely recommend it to anyone that is looking for a memory card for there home surveillance, especially if they plan on being away from home for a long time, the storage hours are amazing!! I would definitely recommend for any professional photographers as well, or anyone that loves holding onto family memories (such as myself) this is definitely the ideal memory card for you! ...My existing 32gb stock dashcam card finally gave in after 6 years of use and constant rewriting every 4 hours. The storage is amazing. This new card quadrupled my capacity and seems so much responsive with playback and recording even at higher resolution. ...STORAGE IS AMAZING"
