they look good if you have your back seats in, if you strip the back of your car out and have a show cage it looks really sh1t because you can see the pathetic brackets and the fact that the cage is 'floating'.
i had one for a few months, had it in and out several times before i decided to take it out and sell it.
it just got embarrasing when people said 'is that a proper roll cage?' and then i reply saying 'no it isn't, its a show cage. Doesn't do anything except possibly kill me if i roll the car.'
as far as fitting them goes, about 20 to 30 minutes normally and about 2 minutes to remove them, i found the best way was to assemble it in the car with the front seats pushed forward and then slide it towards the back, no need to remove the back seats imo.
