this review was written on May 22nd, 2025. be sure to check more recent reviews to see if the issues mentioned below have been resolved.after about a week with the Redtiger F77 V2, i can say with confidence that, for the time being, this is not the dash cam you want. the 4k front and rear is cool, but it covers up a not good and in some cases bad firmware. this review may sound harsh, but expectations are high for such a high price tag.my biggest issue is how it records. normal dash cams will record in a loop, and if told to, will save X minutes of that loop. the F77, instead, records in blocks of video either 1, 3, or 5 minutes. if you tell it to save a video, it will only save that current block and nothing else. it will even wait to save the video until the current block has completed.audio quality is as expected for a dash cam, nothing to write home about, but better than an Xbox 360 party voice chat. the screen is also really nice and responsive. wifi is also easy to use and fairly reliable. if you currently have a dash cam hard-wired with a USB-C power connector, the camera will likely work fine. i changed from a Viofo A229 Pro and was able to reuse the cable for power and the rear camera with no issue, so no need to fish out the wires and re-run new ones.G-trigger parking mode is also useless, as it turns off the camera until a force within the trigger is detected, then it turns on and starts recording. this whole series takes 5 to 10 seconds, long enough for the person to hit and run and you have no evidence at all.the rear camera mount is also incapable of correctly aiming for a steep rear window, like most performance coupes have, so you have to file down the stops on the mount to make it work. also dont forget to tighten the 2mm hex bolt that stops the camera from rotating every now and then, or else it might need some of those little blue pills they become so floppy. this assumes that the double-sided tape actually holds, because mine certainly didnt and i had to JB Weld the front camera mount to my car's front camera shroud.i also hope you like seeing your dash, because you will be seeing it in reflections all the time. no CPL filter is being currently made for the F77 at all. there is also no compatibility with external storage. you record to built-in storage only, but can transfer footage to an external microsd card up to 512GB in size.honestly, unless front and rear 4k 30fps is at the very top of your priorities and nothing else matters, dont get the Redtiger F77 V2. and even then, i have heard about some issues with the video compression, but i did not check that for myself. had i known the issues i would have with it, i would not have spent $330 on it. i e-mailed them about my experience and suggestions, but my response felt like it was AI-generated and equivalent to an inbox that leads to the trash. if Redtiger fixes the firmware issues, i will definitely consider using it again, but for now, i am only keeping it installed until i find another dash cam and can get a replacement front camera shroud. its better than nothing, but not by much. quite a shame given the very capable hardware.Edit: Redtiger contacted me about this review, and after talking a bit, it sounds like they are currently working on improving the firmware as well as the hardware shortcomings. one thing they specifically mentioned was a redesign of the camera mounting hardware to reduce or fix the "losing torque" issue. this is good, and shows that they really do care about making a quality product. they also offered a full refund. i went ahead and raised the rating from 2 stars to 3 stars because this kind of communication is fantastic. however, in it's current state, I cannot give it a higher rating. after all, this is a review of the camera, not Redtiger as a company
