I've had the K&F Concept selfie stick for a couple of weeks now, and it's definitely been the most versatile and useful stick I've had. K&F make some excellent photo/video accessories and this is one that definitely stands out.As selfie sticks go, this is a chunky animal. It's much bulkier than any other stick I've owned and that's because it hides an extension pole that just keeps going. I couldn't quite believe how far this thing extends. I was testing it in the park while playing with the dog and a couple walked past us and stopped to ask what it was. The guy wondered why I was waving a fishing rod around.The stand-out features for me were:Obviously how long the selfie stick is (coupled with an Insta360 camera I got some excellent footage in locations I wouldn't otherwise have reached).Both magnetic mounts (for my iPhone) and 1/4" screw mount for action camera, which can actually be used at the same time.Legs that open out into a wide, stable base (within reason. obviously a very extended pole with a heavy camera would be pushing your luck).A couple of things I didn't like quite so much though. The handle is quite thick and the smooth plastic material doesn't make it the nicest thing to hold. A textured, or moulded rubber grip might have been nicer to hold.The legs are a little difficult to open out. You really need two hands to open them out as one leg always got stuck.Additionally, the remote control that attaches to one of the legs was always getting knocked off. Whenever I put the stick into my bag it would always fall off so it ended up being put in a drawer and likely never used again.As selfie sticks go, despite a few minor issues, this is a impressive bit of kit.
