I posted a 5-star review for the umbrella already, so this is for the auger. What you DON'T SEE is the large knob on the other side of the images, which is what you turn with your hand to tighten the internal horizontal screw against the umbrella pole that sits inside the auger. That single, large internal plastic screw keeps the umbrella pole tightly secured inside the auger. The screw inside the auger pushes the umbrella pole against the inside of the auger, not into a hole in the umbrella pole or anything. Not even the manufacturer has a picture of the knob, or inside screw. Horrible marketing, just ******. I almost didn't buy it, because I had no clue how the umbrella stays securely inside the auger. THE INTERNAL AUGER SCREW IS BEEFY, and looks like it'll never come close to breaking. Also, there are 2 HOLES on the neck of the auger (seen in pics). We took a small cable key chain and ran it through one of the holes, then attached a small caribiner to the cable key chain it so we could then clip the auger to the umbrella carrier's handle. AUGER WONT FIT INTO UMBRELLA CARRYING CASE. We haven't used the auger yet, but it looks like this best will do the job!
