One sound that always means the same thing.
The click is a marker, not a command. It tells the dog precisely which instant earned the reward, and that precision is the whole reason clicker training works faster than praise alone.

Why you'll love it
A dog cannot connect a reward given three seconds late to the thing it did. A click lands in the exact half second the behaviour happened, and the treat can then arrive whenever you manage it.
'Good boy' changes pitch, length and tone every time, and dogs read all of that. A mechanical click is identical every press, which is why it becomes a reliable marker faster than a word.
A clicker carries a few metres. A whistle carries across a field, which is what recall training needs once the dog is off lead and out of conversational range.
Good fit if
Look elsewhere if
Dogs connect a consequence with whatever they were doing in roughly the last half second. Praise arriving two seconds after a sit has already missed the moment, and the dog may well have started to stand. A marker solves the timing problem by making a distinct sound at the precise instant, so the reward can arrive later without the meaning being lost.
A click is better than a word for this because it is identical every time. Your voice varies with mood, volume and whatever else is happening, and a dog has to filter that. A click sounds the same on a wet Tuesday as in a training class, and it is a sound that occurs nowhere else in the dog's life.
Before it can mark anything, the click has to mean something. Spend a few short sessions doing nothing except clicking and immediately giving a treat, twenty or thirty times, with no behaviour required. The dog learns that the sound reliably predicts food, and at that point the click becomes worth working for on its own.
The rule after that is absolute: every click is followed by a reward, even a click made by mistake. A click that sometimes means nothing stops being a reliable predictor, and once that happens the tool has lost the property that made it useful. Treats can be small and can come from the daily food allowance.
The whistle does a different job. Where the click marks a moment, a whistle is a recall cue that carries across a field far better than a shouted name, and it does not carry your frustration with it. A dog that has learned to come to a whistle pattern will often respond when it has stopped listening to its name entirely.
Build it the same way. Pick a simple pattern, blow it, and produce something excellent every time, at first with the dog beside you and then at increasing distance. Do not use it when you cannot enforce or reward it, because a recall cue that goes unanswered a few times becomes a cue the dog has learned to ignore.

The details
Loved by real pet parents
Every clicker I have owned before lived in a coat pocket and was therefore never on me at the moment it mattered. The elastic coil sits on my wrist and it is there for the whole walk. Three weeks of that and her sit is instant rather than eventual.
Outside on a field the whistle is exactly what I wanted for recall, it carries right across and he turns every time. Indoors it is far too much and I set both the dog and the cat off the first time I tried it in the kitchen. Learn from me and test it in the garden.
I had been marking with my voice and getting nowhere, which makes more sense now I have read why. The click is identical every time, and she worked out what it meant in about two sessions. The treat can then come whenever I manage to fish it out of the bag, which is the part I had been getting wrong.
Clicker at one end for close work and the whistle at the other for when he is a field away. Not having to carry two things on a walk sounds trivial and it is the reason I actually use both of them. At 45 g it is nothing on the wrist.
No issue with the click, it is consistent and she responds to it well. The elastic coil is a snug fit on my wrist and after an hour it leaves a mark, so I have taken to hooking it round a finger instead. It does the job and I would simply like a slightly looser strap.
Bought it for the dog and ended up teaching the cat to come in at night with it, which I did not expect to work. The click is quiet enough not to startle her and she is now faster to the back door than he is. One tool, two animals, forty five grams.
His name gets lost in the wind at any distance and he simply did not hear me. The whistle carries the full length of the field and he turns on it now every time. We spent a month pairing it with food at short range first, which I would recommend to anyone.
The clicker itself is consistent and I have no complaints about the sound it makes. The button is a small raised disc though, and in gloves in January I press the body of the thing instead and get nothing. Fine for nine months of the year and I take a glove off for the other three.
We started on the second day she was home, clicking the instant her bottom touched the floor and feeding straight after. By the evening she was offering sits to get the click. The consistency is the point and a plastic mechanism does that far better than I can with my voice.
Good questions
Yes. The click is a promise that a reward is coming, not the reward itself. Charge it first by clicking and immediately treating, thirty or so times, before you use it to mark anything.
Audible. It is a standard pea whistle, not an ultrasonic dog whistle, so you will hear it and so will everyone else in the park.
Yes, clicker training works well with cats and often better than with dogs, because it does not rely on the cat wanting to please you.
Yes, at least while a behaviour is being learned. The click predicts a reward, and if it stops doing so it stops working. Once a behaviour is fluent you can move to rewarding intermittently.
Audible. Silent whistles work in the ultrasonic range that dogs hear and people do not; this one you will hear yourself, which makes it easier to be consistent with the pattern.
Yes. Cats learn from markers exactly as dogs do, and clicker training works well for cooperative care like accepting a harness, a carrier or nail handling.
