Grazer sound interesting... but how much hay does it really hold if it's only 12"? Web site says something like "give a bale and your horse will be entertained for hours." But the video shows the user putting on only ONE flake of hay. My horses go through over a bale of hay a day, if not on pasture. Am I really supposed to go in and add another flake every half hour?
It's 27.5 inches wide along the wall and 12 inches deep from front to back to the wall. It's also 27.5 inches high. If you do the math, it has over 5 cu. ft. interior space. I don't know how much space the spring takes up. That seems to me to be enough room to put in a whole bale, although the dimensions are a little odd for bale dimensions.
The Grazer is a great product! The last place I boarded used them, and it was particularly beneficial for my nervous hard-keeper, who habilitually walked her hay into the ground. She ate every bite and actually gained. I have every intention of getting them for my stalls when my barn is completed.
The spaces between the bars are not big enough to get a foot through, except possibly with foals. (But you run the same foot risk with foal feeders, so it would be to the descretion of anyone with babies to determine if they felt it was safety hazard.) They hold quite a bit. My girls were each getting 4-6 flakes 2x a day, which loaded easily.

I like the Health EZ Hay Feeder...and I think it answers some of your requests...slows them down, conserves hay, safe and portable, which is where the other feeder gets stuck! Oh and mine holds about 5 flakes or so, depending on the hay....
Check out www.perfecthayrack.com. Sturdy, durable, and SAFE. Heavy-gauge powder-coated steel, with flexible front bars. Thoroughly tested on many different kinds of horses in my own barn with NO problems over the course of more than a year. Can easily fit a bale of hay in it, or just one flake. All the hay slides down and to the front because the bottom plate is angled forward. Slows 'em down, keeps the hay uncontaminated and off the ground, and promotes healthier "head-down" foraging. I'm currently testing an optional grid to either supplement or replace the vertical bars to slow 'em down even more.
Whoever said money can't buy happiness never owned a horse.
I'm going to be using them this winter in the sacrifice paddocks so I don't have to waste 1/3-1/2 bale of hay/day, not to mention having to clean up the mess in the spring. I'll be hanging the hay nets on the fence posts and side of barn. I may even use it for my one horse that does crap and pee on his hay.
