Review on Foldable Drone Range Extender Signal Booster Antenna - Compatible with DJI Mavic 🔋 Mini, Mavic Pro, Mavic 2 Pro/Zoom, Mavic Air, DJI Spark Remote Controller - 1 Piece by Chris Estes

This would be a great product if there was a slot in the top of the extensions to properly mount the antennas. With no slots at the top, the extensions moved everywhere every time I moved the remote. I just can't understand why this obvious question was overlooked. I had several different brands and they all had slits at the top and bottom that held the extensions securely in place. If there's a reason this particular brand decided to omit the extra slot at the top, the explanation remains a mystery to me.
