I bought this set of propellor guards so that I can fly my DJI Mini SE indoors during winter. They fit perfectly and saved my drone from damage when I bumped into the wall once, and again when I clipped a light shade from the hanging living room light. In both incidents, the drone was still flying after the collision. I certainly recommend buying the 360 propellor guards when flying indoors or in forests with lots of obstructions. The only caveat is that the propellor guards bring the drone weight over 250 grams - 263 grams to be exact - so you may have to register your drone to comply with drone laws in Canada.
