What is Reddit's opinion of Giottos MH1304-110C Professional Mini Ball Head?

From 3.5 billion Reddit comments

1. Go to Home Depot and buy 2 x 2-inch spring clamps, 2 x 1/4"-20x1/2" screws, and 2 x 1/4"-20 nuts. Your total cost for all of this should be under $5.
2. Order 2 x Giottos MH1304 mini ball head. These are around $20 each.
3. Unscrew the Oculus sensors from the stand base. The separation point is roughly 1 inch below the sensor.
4. Screw each 1/2"-20 nut onto each screw. The nuts act as spacers.
5. Pass the remaining bit of the screw through the little hole on the clamp, near the clamp tips.
6. Screw the mini ball head onto the screw. Make sure the ball head is tightened down so it doesn't just spin forever.
7. Screw the Oculus sensor onto the mini ball head.

You now have an awesome clamp mount that will allow you to mount your sensors to any shelf or desk surface that's less than 2" thick, super-fast and easy. Side note: this clamp mount works for anything else that accepts a 1/4" screw as well, including small cameras, flashes (with the appropriate hot shoe), webcams, microphones (1/2" to 5/8" adapter may be necessary), etc.

In terms of where to mount, Oculus prefers that the first two sensors you set up are within 6 feet of each other, on one side of the room. However, you do not need to do this. I often just mount mine on opposite corners of the room (the same way an HTC Vive is set up) for better roomscale experiences. Note that you'll need a USB 3.0 extension cable to do this. I've had good luck with this 5m one for $15. The Oculus software will complain that they're too far apart but you can still hit the Next button and everything will be fine. I recommend mounting them 2-3 feet above head level, pointing down at roughly a 30-45 degree angle so that they cover the entire area. Make sure the play area you intend to use is visible to the sensors even while kneeling/lying on the floor. If they're not, move/re-aim them.

All of that said, if you can drop an extra $60 for a third sensor, I'd recommend ordering this one which is bundled with a 5m USB 2.0 cable. Note that USB 2.0 is fine for the 3rd sensor but not for the first 2 because tracking gets impacted, if it even lets you get past room setup. If you do end up getting a third sensor, mount it somewhere in the room opposite the other two so that you have a sort of triangle. This should give you best-case scenario roomscale tracking. Note that you'll need to get a third clamp, screw, nut, and mini ball head for your third sensor unless you just want to set it on one of your shelves.

As a side note, there are many mini ball heads on Amazon that are cheaper (by up to half) than the ones I linked. I'm a photographer so I had these lying around. However, I've used cheaper ones and they suck. If you can afford them, get the Giottos.

Yep! I use these. My favorite combo is the Superclamp you use here plus a Giottos MH1304 mini ball head.

Another thing you can do (which works better for some scenarios) is grab some of these clamps (note: you can get these for about a dollar each at Home Depot) and a 1/4"-20 x 1/2" screw + one 1/4"-20 nut. Put the nut on the screw, pass the screw through the hole in the clamp, and screw on the ball head for just the right amount of screw clearance. Then clamp it to any shelf or desk surface super-fast. Superclamps are more robust, but considerably more expensive and occasionally don't fit where these clamps do.

One other option is to use drop ceiling clamps, again, with the same kind of mini ball head. Do not buy them for $20. These can be found for $3-5 (and used to be that much on Amazon) but right now someone is selling them for a lot more. Note: drop ceiling clamps are susceptible to bouncing if the drop ceiling has a floor above and it isn't stable, which can potentially cause tracking issues. YMMV. I've never had an issue with it but it's been mentioned before that it could be an issue. If not, they're extremely low-profile, clean, and simple to install. I used to use them in my office and they worked fine.
