Gadgets, decoded

Before you buy the gadget, find out who made it.

Every review here will answer five questions. Until the first ones are published, here’s how to check any gadget yourself, with the official tools the pros use.

The five questions every review answers

  1. What it's for

    The problem it solves, in plain words, and who it's actually for.

  2. Who makes it

    The maker and where it comes from, where the FCC ID, a lab mark or trademark records can show it.

  3. Cheap copy or real alternative

    Whether it's the same thing under a new name, or genuinely different.

  4. What buyers report

    Recurring pros, cons and failure patterns, with where they came from and their limits.

  5. The verdict

    An explicit call on whether it's worth the money, and for whom.

No reviews are published yet. We only give a verdict on something we can back up.

Quick tip47 CFR 2.925

Flip it over and find the FCC ID

A certified device has to carry a label showing its FCC Identifier, printed after the words "FCC ID." The label has to be readily visible to the buyer at the time of purchase. An FCC ID has two parts: a grantee code the FCC assigns permanently to the company that applied, and a product code that company chooses. That's why the ID points back to the applicant, not just the product.
