ANSWERS

FREQUENTLY ASKED QUESTIONS

The essentials before you open a case — investigations, verdicts, credits and payments. 43 answers in the full archive.

What does Grossmeister actually do?

It investigates an appliance before you buy it. You provide a product link, a model name, or a description of what you need — the system analyzes performance, efficiency, features, reliability signals, value and long-term ownership cost, then issues a clear verdict such as BUY IT, CONSIDER or SKIP.

Can I paste a product URL?

Yes. Choose the PRODUCT LINK tab and paste the URL from any retailer or manufacturer page. The system identifies the product and investigates it. Demo investigations use sample data where live fetching is unavailable, clearly labelled as such.

Can you detect overpriced products?

Yes. The Price & Value analysis compares the asking price against an estimated product value derived from specifications, features and category benchmarks. The result is labelled GREAT VALUE, FAIR, ABOVE MARKET, OVERPRICED or UNKNOWN.

Can you estimate ownership cost?

Yes — it's a signature feature. The Ownership Cost section combines purchase price, energy, water, maintenance and consumables over a 5-year horizon, with each component labelled as an estimate.

How does credit pricing work?

Everything is priced in credits, and packages start at 50 credits. You spend credits from your balance on the investigations you need — no subscriptions, no trials.

Is there a free trial or demo plan?

No. There are no trials, demo plans or free tiers. The entry point is a 50-credit package — this keeps the investigation queue fast and the analysis honest.

THE NEXT APPLIANCE YOU BUY — INVESTIGATE IT FIRST.

A five-minute investigation can save five years of regret.
