A priori skeptical, I trusted the advice already. From my side I'll meet also the advice that is good value for money. Indeed he did not expect for that price to have the same quality as in GoPro, and this is normal .. However accessories are useful and for some the difference in quality with official accessories is minimal (the harness chest and head are really very good!) For me the only accessory that you can not count vrmt is the pole which is a somewhat limited level quality. Very good for a selfie or the other but no comparison in assiduous use with a pole at 50 euro ... so do not buy the pack for perch but the rest is not bad.
