Are All Triple A Batteries The Same Size

2/3 of a stop is a good value for my needs. the full stop was too much and 1/3 not enough at all.

Pretty good. It also charges triple A batteries as well.

Same as the classic triple riser beefy baby stand you'll find in every studio lighting package, equivalent to the ones made by American, Matthews, Modern, etc. The same stand is also available in 35 and 45 versions from Avenger, which are shorter and taller than typical beefy babys, respectively. This one is the more common size. Typical nice and smooth Avenger quality. My only complaint is the three bolts that connect the legs to the stays are slightly too long and the protruding threaded end can rip sandbags. Not an uncommon issue, though, and is easily fixed by adding six stainless washers so the nylock nuts sit flush at the end.

Same battery size as the GoPro brand and works just fine!

Triple 'A' batteries are light and simple to replace. The instruction booklet is excellent! Read it and practice until it it's second nature. Once learned the use is infinite!

Same as the last one.

Same as above!

Same as came with camera, zero issues. Getting good life out of these Nikon Batteries

I got a 14-inch version for narrow spots, and that worked great, but I immediately got this 24-inch size because my camera requires filling the viewfinder for Custom White Balance and the 24-inch size allows me to shoot from far enough away that I do not get into the light for the shot. It also is a little more polite if you are asking someone to hold it for you and you don't have to invade their personal space. I tried the triple-tone target out of frustration with inconsistent results with hard-surfaced gray/white cards and exposure disks of various types. I have to deal with a lot of reflective surfaces and confined spaces doing product photography. The triple-tone fabric is easy to set up because it is less susceptible to reflecting light when metering, and you can toss it almost anywhere. Other reviewers have expressed concern about it not being a certified tone, but that doesn't seem to be an issue, maybe because we are measuring relative color variances. The triple tones do seem to make a good exposure target for setting up the shot and also for post-processing for setting the software eyedroppers and for general evaluation of the scene. The white, semi-luminescent reverse side is quite effective. In an early-morning outside shot a couple of days ago, I metered about a ten percent lux boost reflecting soft light into a corner of an electrical enclosure from about five feet away. It is light weight enough that I could just hang it with some gaffers tape.
