DJI Mavic 4 Pro Propeller Guard

These guards are very useful if you have to fly the Mavic 4 Pro indoors or in tight spaces. First thing to note - they are massive! With the guards fitted, the Mavic 4 Pro is 710mm wide and 620mm long (approx. 28" x 24½")! The first picture shows a Mini 2 SE alongside for scale. The guards are each marked to denote which arm they attach to: LB=left back LF=left front RB=right back RF=right front I found attaching and removing the guards took a bit of practice and it seems easier to fit the front ones before the back ones. Once they're locked, they stay securely in place while the front and rear guards attach together to further increase rigidity. Holes in the back guards enable the strobes under the motors to remain visible which will be good for night flights and dark rooms! Unfortunately, I did find a problem with the left back guard because it wouldn't lock around the drone arm at first. The locking part of the guard seems to have been moulded slightly out of spec but a few minutes light Dremelling fixed the problem and the guard now attaches and locks fine. Not worth returning over but definitely loses a star. Probably an early batch issue. If the drone is sitting on a flat surface, the back guards measure 135mm (5 5/16") tall and the front guards are 88mm (3½"). The guards provide enough lateral protection to make flying near walls or pillars a lot less scary but vertical protection isn't quite as good. While the propellers are unlikely to strike a downward facing surface like a ceiling, two of the drone's top-most obstacle avoidance sensors sit just proud of the guards so they could come into contact. Obstacle avoidance itself seems to work fine with the guards on, but it will likely need to be switched off for the drone to move in anything smaller than a warehouse. Did I say the guards are big?! DJI's claim of 188g for the guards is accurate. I measured the total takeoff mass increase from 1.06kg to 1.25kg. Flight time seems to be reduced by 10-15% when mostly hovering with very slow manoeuvres. I probably won't use these guards every day, but having the option to fly the Mavic 4 Pro in confined spaces now is very welcome. Recommended.

What a disgrace! Clearly we are now seeing the an attempt to claw back profit by lowering quality. The rear left clip does not fit and resulted in mine breaking rendering the guards useless. Even the other 3 clips had to be uncomfortably man handled to get those on. Some review mentioned a bad batch, the problem is the whole Mavic 4 pro experience is more than a little bit disappointing. Purchasing the so-called "creator combo" which has no ND filters included to no pro-res support etc is leaving a bitter taste in my my mouth. I may just end up sticking with my Mavic 2 pro as the quality of that drone including the propellor guards for it are superior.

なかなか入手出来なかったので、サードパーティーの製品を購入したが、結局 純正が一番良いです。（振動、耐久性など） サードパーティーのものは、安かろう悪かろうですね・・・

1箇所すごく硬くて装着出来なかったので新しいものと交換してもらいそちらはスムーズに装着出来たので最初のは不良品であったのだろう、見た目しか検品しないのかな？ Amazonのその後の対応が問題でカスタマー挟んでもAIなのか解決したのに返金対応のメールが何度も来て着払いで送りつけるとか言っててどうにかならんのかな？
