It it an excellent product that worths every cent you pay for it.
In my opinion, a necessity for every GoPro user.At least 50% more
stamina than its' original one in real action. Using the
"KomputerBay 32GB Class 10 SDHC Ultra High Speed Memory Card"
records in 720P wide 2 hours+10min without any rec-stop-rec use,
or 1 hour+30 min if your finger feels happy playing with shutter
button all this time.
