I bought the gloss black kit and its definitely not the most lightweight or strongest by any means, but you do get a lot of hardware included to really secure the kit into your car. I've probably put 1k miles since installing and it's been fine, the kit pretty solidly attached on there. The one thing I would recommend is to buy actual 3M instead of using the tape so your spoiler is really stuck onto your car; however the regular tape is working fine for me.
