mine came with them and a hard top and like em both. with it in that configuration i feel it's fairly secure. the sliders don't open all that much but have learned to deal with drive ups(got pretty good at dunk donuts
) i like that they are glass in the winter and can scrape em. good for cooler weather and when i need more air i just pop em off and toss em in the back-fit pretty good behind the rear seat. they are fairly quiet and have not had any leaks. my opinion, they beat zippers and folding down and you have more controll over how much air you let in. for me it would either be these or full doors-not crazy bout the soft uppers.
