Needs improvement. It looks like this product has been rushed to catch the sales trend. The clasps come off too easily. A single collision with a wall or object can unhook the guards and get stuck in the propellers. The result is probably worse than no protection at all. My advice: instead of rushing to market, find a brand that has perfected their product. In this case it will likely be direct from DJI or a brand with a few unpaid reviews.
