What to know before buying

Listing details to confirm

The listing's battery details are inconsistent: it calls the unit rechargeable and lists a charging cable, but identifies the battery as Lithium Polymer in one field and Lithium Manganese Dioxide in another. It also gives a 5 g weight both separately and alongside dimensions, so confirm these details if they matter to your purchase. The listed accuracy is 0.01mW/m², while magnetic and electric readings use different units.
