I havent used the drone a great deal over the last few months so cannot comment on whether it can stand up to alot of use the quality seems ok though

The top section of the backpack if you look at the shoulder straps as being the bottom unzips like a suitcase giving easy access to the catch for the original foam case so no need to remove the dji case completely

The original foam case the the p4p comes in fits snuggly inside this backpack so although its made of soft material the drone is still nicely protected inside
