HeiyRCPropeller Guard for Holy Stone HS720 HS720E Drone Anti-collision Props Protector Blades Bumper Safety Accessories

On my very first flight, one of these ruined my motor. There's not much that go wrong in installation, it seemed, but I noticed my drone wasn't flying properly and landed it. I had to unsnap each one, the only thing you can do. I noticed the back left motor had a mark around it and was extremely hot. These come up and around the motor so they either need to give some more space or, gosh, I don't know. Regardless, I'm pretty upset I bought these. I've checked and re-checked, but that one is always going to be too close to the motor for comfort. The drone itself is only a month old and hasn't been crashed. Sigh.Now I not only have to return these, but I can't seem to find a left rear motor or arm and motor combo. This is awful. Gosh, not to mention that a landing gear set I bought from them also failed recently and I had to put it away. I'm going to be steering clear of these folks from now on.

It is very much a no instruction installation. If you follow the RF, RR, LF, and LR that is written down on the back of the guards you can install those without any problems!

I am giving these 2 stars because they fit. They feel like they wouldn't last long or take any punishment. Disappointed with this purchase.

Wont stay on keep your money complete trash

Horrible design. Causes the drone to fly randomly at uncontrollable speed and it eventually crashed into a wall, broking the galvanized guard and the propeller.DO NOT BUY..... BAD PRODUCT...
