What to know before buying

The title claims an adjustable range of 22–440lbs, but the details specify only a 440lbs tension level and do not confirm the lower setting or adjustment increments. The listing also gives parcel dimensions and mass as 44.4 x 24.2 x 5.9 cm; 10 g, which should not be treated as confirmed product dimensions or product weight. The listed 17.5-inch expanded size is a separate feature claim.
