I need a new rack and saw the ad looks cool notcheap but was wondering if anyone has seen one or uses one?
I was looking at the single $270.....so not as a bad a a Thule but not cheap either

I have no experience with one, but they have been discussed here on the forums before. They seem to be well reviewed by people who have them and not trusted by those who don't have them. You'll also likely get a new user who comes in and makes their one and only post on the forum a glowing review of them. Not saying they'll be a shill (just implying it).

Never seen a poor review on them but they do seem pricey for what you get

compared to?

I have the mini bomber that holds 2. I bought it for the convenience of having a rack that I can remove and that doesn't require any installation/weight penalty/mileage penalty. I haven't used it much but when I have it held my bike/s really well.

Caveat though: their customer service sucks. I emailed them twice and messaged on their FB account and no response. I guess calling them is the best way to go.

It looks well made is it easy to use?
The set up with the water ....ugh but I like the idea of it's on it's off.
Is the bike sturdy?

I know a pro racer who uses a Seasucker rack regularly. It lets him transport his bike on any rental car (and still have plenty of room for luggage and gear) so he doesn't have to pay the 3x price for the big SUV (and hope that there is actually one on the lot when he arrives). He says the rack has always worked perfectly.

I was tempted to get one so I could carry two bikes with my Corvette (which can't fit a trailer hitch). But it turns out yearly registration and insurance for an old compact pickup truck is about a third the price of the Seasucker mini-bomber (and the truck can haul stuff other than bikes). On the other hand, the Seasucker probably won't leave oil drip stains on your driveway

I've never heard of anyone having problems with the cups losing vacuum or dropping a bike. However, not the best if you ever want to lock your bike to the rack and leave it out of your sight. I'd also be concerned the device could be stolen if you leave it on the roof while you're off on your ride. Every so often you're supposed to disassemble it and lubricate the internals.

I take the 2 minutes to re-install it on my roof. This is not an issue at all.
