What reviewers found
-
TrailCamPro (US) review (trailcampro.com) Retailer review
Scored it very highly for picture quality and trigger speed, measuring long photo battery life but only a few months when shooting video, and found the menu wording awkward.
Summaries are ours; follow the links for each reviewer’s full verdict. Reviews marked “Retailer review” come from shops that sell the camera rather than independent publications. Where Which? is listed, we only note that the camera was in its test — its verdicts are for members.
