Question about Ryze Tech Tello

I'm sorry, I haven't tested it. Until today, I always flew within visual range so that I could always see the hardware. This way I could keep the drone under control using my smartphone or Tablat (Tello app). I took the reception ranges from the operating instructions. The battery power decreased quite a bit early on. But what can you expect for just under Fr. 90,-- drone price. I use this drone as a toy with my grandchildren. - Best regards

Not yet used. Waiting for remote control. Does not stand approx. 100m?
