I think for the price you get a lot ! The suction cup is amazing ! I put it on a kitchen sink for 2 day, and it held pressure, and it was a texture surface. It a large suction area. When you start to pump, it feel it does nothing, but if you keep pumping you see it does it things and securely hold into place. It just cannot hold a good amount of weight, it really stable as well. You have a lot of connection point on the suction cup base making it versatile.

And for the price, the suction cup alone would be a good deal, but you also get some really nice magic arm. Some of the nicest I got, that is super nice to use, but doesn't hold that much weight, but enough for small camera. I didn't use the phone holder, but the gopro holder is holding very well off the magic arm.

The only thing you don't get is a storage case. I would have included a larger plastic bag to hold the small accessories together.

No idea if it hold the vacuum for a lot of use, but so far, I have nothing bad to say... Good job at K&F for making this at this price ! Would be nice to see a cheap 3 cup car camera setup with those suction cup !
