They were packaged in a long tubular package that was well protected from shipping problems. The supports themselves were individually wrapped. At first glance they looked high quality, they had no leaks or dust, they looked like they were fresh from the factory. It takes 10 minutes to install on the hood of a car, all you need is a flathead screwdriver, nothing else. There is a small notch on the top. Give it a little tug with a flathead screwdriver and it pops out of the bracket. The bottom comes out right after the top. Once the new ones are installed on the car I tested them, the hydraulics seem to be too powerful than the original hence the hood lifts itself so I suggest not holding the hood while the hydraulics are working. To work. You don't have to worry, the main thing is that the hood does not fall off when you work on the engine. They offer enough support, in fact once installed only one side will hold the cargo area without needing the second side, this speaks to the support they add to the hood. In general, I like the product so far, I have to take a look. Durability but also perfectly satisfied at the moment.
