An in-home usage test (IHUT) sends a product to people's homes and asks them to use it as they normally would. Scores from a questionnaire tell you whether people liked it. Video tells you why: you see how they open it, where they put it, what they do with the instructions and the look on their face at the first try.
Here is a day-by-day plan that works for most consumer products, from food and drink to personal care and household goods.
Before the study: logistics decide the timing
The product has to arrive before day 1. Plan shipping first, then invite participants once their parcel is on its way. On Zolensa, day 1 is the day each participant signs the consent form, so people whose parcels arrive later still get the tasks in the right order.
Decide also:
- Branded or blind? In a blind test, plain packs avoid brand effects. Ask people not to show other brands on camera.
- One product or several? For a comparison, split participants into groups, one per product or test cell.
- What must stay confidential? Unlaunched products need a confidentiality tick box in the consent form.
Day 1: unboxing and first impressions
Ask for a video before people read anything: "Open the parcel on camera and tell us what you think as you go." This catches the first reaction to the pack, the size and the look.
Then a few quick questions: first impression on a rating scale, and what they expect the product to do, in their own words.
Day 2: first use
The most important task. Ask people to film themselves using the product for the first time, in the place they would normally use it. Watch for:
- whether they read the instructions, and when
- where they hesitate or get it wrong
- what they say at the first taste, smell or touch
Follow with a grid: rows for the attributes that matter (for example taste, texture, ease of use, smell, value), each on the same scale.
Days 3 to 10: real use
Now the product becomes part of normal life. Keep the effort small. A repeatable "every time you use it" task collects short entries: a photo or a short video, and one or two quick questions. Add one evening task midway, such as "Show us where you keep it now, and why there."
This is where you see what a questionnaire misses: the product moved to the back of the cupboard, used for something unexpected, or shared with someone else in the home.
Last day: the verdict
Repeat the same grid and ratings as on day 2, so you can compare first use with the end. Then ask the open questions:
- "Would you buy it? Why or why not?" as a short video
- "What would you change?"
- A recommendation score on a 0 to 10 scale
Following up during the test
The most useful insights often come from a follow-up. If a rating drops between day 2 and the end, ask why, in the same thread as the entry. If someone does something unexpected on video, ask about it the next day.
Analysing an IHUT
Put the structured answers side by side: grid answers and ratings from first use and from the end. Then look for the reasons in the videos and notes. AI can suggest themes across all entries, each with quotes and the moments they come from. Check them, keep what holds, and mark the best clips as highlights.
For the debrief, a short highlight reel of first reactions and final verdicts makes the results real for the client. Ten real people trying the product say more than a slide of averages.
Common mistakes
- Starting before the parcel arrives. People cannot film what they do not have.
- Asking for opinions, not use. "Show us" beats "tell us".
- Changing the questions. Use the same grid at the start and the end, or you cannot compare.
- Too many daily tasks. Short repeat entries keep people going.
On Zolensa, you can run all of this in one study: groups for each test cell, grid and rating questions, repeatable tasks, follow-ups and highlight reels. See the in-home product testing use case.
