This works great, stores in the car when not in use and the suction cup really hold, I've left them on all day here in Arizona heat and no problems, lite weight and dependable, very universal, highly recommended
The Seasucker Talon is very impressive. It does exactly as advertised - about 230+ lbs of force per suction cup to hold you bike on. I've used it a few times now and very impressed with how easy it is to use and how sturdy it is. It does the job and seemed like the only option for my particular car since I couldn't mount any sort of hitch to it. I strongly recommend this for anyone who can't or doesn't want to mount a hitch-based bike carrier to their bike
The only downside is that they are kind of pricey. However, the quality is good and it is very robust.
