Review on Thetford 01664 Plain Valve Cap by James Manning

Through trial and error i found that this product was a complete waste of money. The valve cap did not fit properly and kept falling off, resulting in constant air leaks in my tires. The only pro was that it was easy to install, but that didn`t outweigh the persistent frustration of dealing with faulty equipment. Save yourself the hassle and opt for a different brand..
