The installation went quickly. It took two people less than 3 minutes to install both sides of the tailgate stays on a 2007 Murano SL. They are very powerful and now I push the button to open the back door and stand on the sidelines while the gate opens without my help. The only downside I see is that I now have to use both hands to close the gate. Now if I were an elderly lady I probably wouldn't even be able to close the back door with two hands, so maybe just install a brace for the elderly person so they can still close it themselves? I am VERY happy with the product and the price and will buy again for my other vehicles if needed. I'm sorry that I waited so long to purchase after realizing how easily my tailgate opens once installed. Arrived quickly and as advertised. Excellent product!
