The presentation model, honest.
Also called: Looks-like model · Appearance model · Cosmetic prototype · Sales mock-up
A model built to look exactly like the finished product for photos and meetings, while doing none of the work the real thing will do.
A looks-like model gets the finish, weight and feel right so people can see the product before it exists. It is for photography, pre-order pages and buyer meetings. It works on nobody. The one rule: never let anyone believe it does.
What a presentation model is
A presentation model is the product’s appearance, made real, with none of the function behind it. It has the right ceramic, the right wood, the right weight in the hand and the right join lines. What it does not have is a working heater, a sensor, or a single watt going anywhere. It is a looks-like, not a works-like, and the entire value of it depends on you being clear about which one it is.
This matters because a finished-looking object is persuasive in a way a rendering never is. A buyer can pick it up. A camera can light it properly. A pre-order page can show the actual thing rather than a CAD image with a hopeful caption. You get all of that months before the working product is signed off, which is exactly why it is tempting to oversell. The discipline is to use the persuasion and refuse the lie.
Looks-like and works-like are two different jobs
The functional prototype proves the thing heats, holds and behaves. The presentation model proves it looks like something a serious baker would put on the counter and pay for. Trying to make one model do both jobs usually produces something that does neither well: a working rig that photographs like a science project, or a beautiful shell that nobody trusts because it visibly does nothing. Keep them separate and each is allowed to be excellent at its one job.
The clearest test of a presentation model is this: it should be honest enough that you would happily hand it to the buyer and say what it is, and good enough that they would still want it.
- Passing it off as a working unit in a demo.
- Letting a buyer assume it has been tested.
- Shooting it switched “on” with no caveat anywhere.
- Taking pre-orders without a clear ship date.
- Calling it an appearance model out loud, every time.
- Stating which parts are final and which aren’t.
- Using it for finish, feel and photos only.
- Naming the certification still to come.
How it fits the bigger picture
Presentation model is activity 08.10.03 in Stage 08 Develop. It comes before the functional prototype (08.10.04), which is the model that actually does the work. The two are deliberately split: this one earns the pre-orders and the buyer interest on looks, while the functional prototype, built next, proves the thing performs and survives.
What it can do
Show people the finished product before it exists. It gives you photography that sells, a pre-order page that converts, and a buyer meeting where the object on the table does the persuading. It de-risks the commercial side early, before you have spent the larger money on production tooling.
What it can’t do
It can’t prove the product works, because it doesn’t. It can’t earn any certification, sit a single test, or tell you whether the heater holds 26°C overnight. And it can’t be honest on your behalf; that part is down to you, every time someone picks it up.

Try it yourself
Decide the one room the model has to win: the photo shoot, the pre-order page, or the buyer meeting. Build to that room’s standard and no further. Write your honesty line before you build, not after, and put it in the caption, the deck and your own mouth. If you couldn’t say it to the buyer’s face, you have built the wrong thing.

Project notes: the box that heated nothing

Building a beautiful non-working proofing box in Stockport for the pre-order shoot and a buyer meeting, and the one sentence we made everyone repeat.

Dan and Anna Hartley needed two things at once: photography for the £149 DTC pre-order page, and an object to put in front of a kitchenware buyer. The working unit was still weeks from passing its BS EN 61010 checks. So we built a presentation model: real Stoke-on-Trent ceramic shell, real wood, correct weight, a dummy OLED and a dummy encoder. It looked completely final. It heated nothing whatsoever.
What it bought us
The photos were the actual product, not a render with a wish attached. The pre-order page converted on a real object. And in the buyer meeting the model did the persuading: she picked it up, turned it over, and the conversation moved straight to volumes and margins rather than “can we see one?”
The sentence we made everyone repeat
I wrote one honesty line and refused to let anyone improvise around it: “This is an appearance model. The finish is final; the electronics aren’t fitted yet. Certification comes from the working unit.” It went on the website caption, in the deck, and out of Dan’s mouth in the first thirty seconds of the meeting. Anna worried it would deflate the room. It did the opposite. The buyer relaxed, because nobody was trying to fool her, and a buyer who trusts you reads the rest of the deck differently.
One near miss. A freelance photographer, being helpful, lit the dummy display so it looked switched on and live. We caught it on the proof and reshot it dark. A glowing screen on a box that heats nothing is precisely the small lie that turns an honest looks-like into a problem, and it is always the well-meaning detail, never the deliberate one.
