I've had a number of K&F Concept products and found them pretty good so far, and this one isn't bad, but it has one obvious flaw that caught me off guard. What you get is an extendable grip that can hold your phone or tablet in landscape or portrait mode. There's a screw thread on one end and another on one side, so you can place the clamp on the vertical or horizontal axis, so you can take landscape or portrait photos depending on your needs and almost independent of your tripod. The thread obviously fits standard tripod screws. The good thing about their design is that there's a button on either side. When you press it, you can pull the clamp out and lock it in different positions against a ratchet. That means you can open it wide. Whether you extend it like that or not, you can then keep pulling the clamps against their spring-loaded mechanism that ensures your grip. That means I can put my phone in the case from the beginning to the end and it's one of the biggest flagships on the market. This mechanism works pretty well and is better than similar clamps I've had and will now discard. The whole thing is very lightweight as it's made of plastic. The other end of the screw thread (the end, not the one mounted on the side) is a cold shoe clamp for attaching camera accessories, which in this case would probably be a microphone. What's the downside? They forgot that phones and tablets belong in protective cases and any assumptions about them should be considered from that perspective. I don't want to take my device out of the case to mount it. Unfortunately, since they forgot that, they didn't take it into account when designing the rubberized clamps, which doesn't account for the perfectly normal extra thickness. There was enough room for that, they just didn't do it. Which is silly. It holds my phone in its case, but when it's in landscape mode, I don't think it's good enough to use it long-term. The middle part is also too thick, so it may conflict with the extended camera lift that flagships insist on for no reason. If it were less thick and the clamp ends could handle a larger radius, this would be significantly better. You can probably ignore this if you're not using a case or are using something incredibly thin. But even without my case, my current phone has flat ends instead of rounded ones, so it doesn't fit well in landscape mode. Which is a shame, as it's just not up to their usual design standard and it's a very predictable problem.
