It does what it's supposed to do but I'm not sure how long it will last. I understand that it needs to be very light to extend battery life and keep the drone very light. My problem is that it has to be removed after each flight when you put the drone back in the case. I feel like the price of 12.99 is nothing short of a steal! My understanding is they should come in a three pack for $5.99, I don't think I'll spend another thirteen bucks if this one breaks. Its production is probably worth a dime, I understand you have to make money if you are in business, but it is too expensive for what it is and how long it will last. I gave it four points just for doing what it's advertised to do, which is to land effortlessly on sand, gravel and tall grass. The four starts I gave it for strength are based on how strong the drone is when attached, NOT the strength of the chassis! One star for durability speaks for itself.
