I brought the OB dry bag on today’s kayaking trip and it worked well. I tried taking a few photos while the phone was in the bag and quality is definitely effected.
However it keeps my phone dry and that’s why I bought it. I’m going to give it an overall score of 4.5 out of 5. The last 1/2 point is for the slightly short cable and the loss of quality on photos, but it’s mostly for the cable. After all you can’t expect photos to look the same if shooting thru clear plastic!
