We were looking into bridgit ramps , but they were super expensive and very inconvenient to buy and ship . These were cheaper and amazon shipping is unbeatable . So we took a chance and bought 6 of them . Spent over $700 to span my driveway . And the difference has been worth it . No more jarring , when leaving and coming home , wish this product would have been available years ago . Prolly would have saved me some alignment money on our cars . The only negatives are that you have to line up the ramps from time to time , if you’re picky about straight lines . They have attachment holes to hook them together , but with what? Also , they had a strong smell or rubber and chemicals when they first arrived . Open these outside . I could smell them in the driveway for the first few days . But all gone now . They have survived many severe rain storms and blazing St. Louis heat , with no issues
