I've been using a K&F Concept tripod for years, and have been very pleased with it, so when I saw their suction cup mount, a jumped on it. This thing is great. It uses a pump to create a great amount of suction that allows it to hold on to a variety of relatively smooth surfaces. I've actually had this on one of my kitchen cabinets by the stove now to read recipes off of for the past two and a half weeks. And it never slipped, never fell, never needed to be re-pumped. It's not even a perfectly smooth surface. This is a stained wooden cabinet. I'm really impressed!

The core of the mount and arm is metal, and you can tighten it down very firmly. It has a standard 1/4" tripod style screw.

It comes with a phone mount and action camera mount, but you can use any of your own 1/4" mounts or adapt one of your larger threaded mounts with a screw adapter. The included mounting accessories are plastic, compared to the metal core, but are still good quality. I haven't had any issues with it, but in the future, when I use this thing outside of a car or something, I'd probably use one of my existing metal mounts with it instead for the added security.

I expected this to be a good mount given my history with the brand, but it's honestly exceeded my expectations. If you're in the market for something like this, I highly recommend this option. This is a legit brand, and they make some good products.
