I bought 2, one for the driver's seat and one for the passenger's seat. It is very annoying while driving and in both cases it constantly loosens with the slightest movement, the belt slips and comes off. It needs constant tightening and during driving it is very difficult to bend down to adjust it being in the 7th month of pregnancy. I almost didn't use it at all.

Very good product for pregnant women. However, it is not convenient if you are wearing a dress or skirt below the knee. It is great with pants
