What to know before buying

Listing details to confirm

The listing gives two different size descriptions: 10.9L x 5.3W centimetres in product details and 10.7 x 5.4 x 1.1 cm for the base plate. Treat them as inconsistent listing dimensions, not a confirmed product defect. The listed 0.03 Kilograms weight is a separate product-detail claim.
