In Ethiopia, Iraq, and Syria, Iranian Muhajir-6 drones proved completely useless. Due to the ineffectiveness of these Muhajirs, Ethiopia purchased Bayraktar TB2 drones from Turkey immediately after the Karabakh War and used them with great success during the conflict in Tigray in 2021.
Incidentally, Russia, which also used the Muhajirs, was also extremely dissatisfied.
It's worth noting that after the Muhajirs' failure on the Ukrainian front, Putin personally approached Erdogan with a request for Turkish drones, but Bayraktar refused.
If all Iranian weapons are as "effective" as these Muhajirs, then it becomes clear why Iran is experiencing a real catastrophe under aerial bombardment
