Anyone reading buying advice should know what the author earns from — and how the texts come about. So both are set out here in full, not in the small print.
How these posts come about
The texts are written together with an AI assistant (Claude, by Anthropic). The basis is my own installations, measurement series and configuration files — nothing is invented, a great deal is sorted. I check and release every post before publication; editorial responsibility rests with me.
All photographs are my own. No image is AI-generated, and none shows anything that was not there in front of the lens.
They are edited all the same, as they would have been in a darkroom: cropping, straightening, brightness, contrast, colour temperature — and masking out meter, serial and device numbers. Those steps are not noted one by one. Where a tool goes further, computing away image noise, adding sharpness or taking an object out of the picture, the caption says AI-edited, with a word on what was done.
Cutting out goes with that. Where the background contributes nothing — a flowered tablecloth, a woollen blanket, a shelf full of clutter — the device stands against a plain surface. Nothing is invented in the process: only what does not belong to the device falls away, and nothing takes its place. The caption says so all the same. Where the surroundings are the point — the wiring inside a junction box, how something is mounted on a wall — they stay.
These notices stand here because a site that argues from measurements should also account for how it comes about.
Where the money comes from
Affiliate links. Some posts link to retailers. If you buy through them I get a share from the retailer, not from you — the price does not change. Every affected post carries the notice above the text, not at the end.
Paid productions. Should a manufacturer pay for a video or a post, it is labelled as advertising, and that label comes first.
My own guides and templates. Planned, not yet available. When they exist they will be sold as a product and described as such.
What I do not do
- No verdict for payment. Nobody buys a review. Whether a device is any good is decided by the test, not by the commission rate.
- No pre-publication approval. Manufacturers do not see texts before publication and may not change them.
- No recommending untested devices. If I have not used something myself, it says so.
- No invented savings. I only state euro and time figures when they are measured. Otherwise it says “not measured”.
Review units
If a device is given to me free of charge or on loan, that is stated in the post — whichever way the test turns out. It makes no difference to the verdict. Devices I bought myself are the normal case.
The limits of what is written here
The setups described run in my homes, with my tariffs, in my buildings. Three locations are not a controlled manufacturer comparison. Differing results may come down to building, usage or chance rather than the device.
Where a setup is not finished, Work in progress is shown above it. That makes it an interim state, not a result.
Licensed work
Anything touching electrical, gas, heating or water installations belongs with a licensed trade. What is written here documents my own approach; it is not a build guide and not an authorisation to intervene in anyone else’s installation.
Questions
If something strikes you as opaque, write to me. A disclosure I missed will be added — with a date.
