Of course if your car is low on Freon that likely means you have a leak. To fix that you would need to take apart all the hose connections and replace the o-rings, then use a vacuum pump to evacuate the system and then add Freon. Of course the cost for all the equipment to do all that is roughly the same as taking the car to a mechanic and saying fix my air conditioner.
That is why god created pressure-temperature charts (that can be found online and normally come with these kits)
That has not been the case for decades. The sealants no longer not 'gum up' internals like in the days of ol. They only react to the presence of moisture* and sometimes cause o-rings / gaskets to swell (making a tighter seal).)
Unless you had a complete blow out, oil is still in the system. Also many of these kits do supply some oil. Also they tend to contain *moisture neutralizers for inside the refrigerant loop (and preventing sealants from reacting where they shouldn't). There are many recharge kits: with oil, without oil, with sealants, without sealants, with UV dye, without dye, moisture neutralizers, no moisture neutralizers, or pure refrigerant if you don't like additives.
But you are right, in a perfect world you'd drop your car off at a mechanic then pickup your revitalized AC a day later. But that $1000 difference in price is where the problem is. $30 does have a few downsides over actually doing a true "repair" but if it fails, you'll be a square one either way.

If you are trying to keep your car for another a few/many years or are hoping to keep the resell value high, consider taking it to a shop.
Assuming you have the money, which many people just don't.
Edited for clarity.
Yes they do have their uses. I've experienced the good and bad. A car I bought had no working ac. I used a kit with sealant and got it filled into the green zone (it had all leaked out) and it worked well for a few months before it leaked out. Ended up replacing the leaky compressor. Another time another vehicle took forever to blow cold. Used the same hose, new can no sealant and accidentally over charged it (not empty, just looked low based off the gauge). Now it had no cold air. Compressor sounded horrible when running. 1000 later it's fixed by a mechanic.
Now, at what ambient temperature should this be used? Is the green area of such gauges calibrated for round 70~75 f outside temperature? (obviously with a cold engine)
FYI, Freon is a R22 brand name, not something commonly used in auto applications. Thanks for the unneeded clarification that no one benefitted from.

People who use this device do not have $200+ to go to service and do full evacuation which is actually not needed if you are just adding 2-3 oz of R134a

And it needs to be at least 65ºF:

You are like the guy in the gun store yelling at everyone saying "clip" while calling everything else by the wrong name.
You sure got bent out of shape, even though if you look at my original reply, I only pointed out the fact that it was a brand; not that it was wrong or they shouldn't use it or that it upset me.
Move along.

Your statement is factually wrong, regardless of how many fake "car dealers" you are quoting. Honestly I would say that automotive AC systems are probably smaller, lower capacity compared to older cars as fuel efficiency standards and vehicle weight go hand and hand. Remember the good ol' days when a midsize car was built like a tank and now they weigh a 1/3 of what they once used to yet are physically the same size? That weight came from somewhere. And "fog coming out the vent" is NOT optimal. I remember that too but you are better off with a 15-20 deg Delta-T as opposed a 30 deg+ drop. You'll turn down the AC long before any humidity has been removed. Yes "colder"...but less comfortable. I bet the inside of that car with "fog" was always musty and you still had visible sweat even if you were "cold." Wonder if there was a connection
