Works well, usually, but trying to hold the nose of an SUP pulling uphill it WILL slip out of your hand. $75 ding repair second time I used this cart. I finally decided to rig a strap system so that I could pull the strap when going over rough terrain or up hill. I see that the company finally realized that this was needed as they now advertise a strap set up much like on the Mule trailer.
Why weren't they invented sooner? They are nothing short of fantastic. Thank you! Brian in Mailibu.
Used this for a windsurfing board. Strap did not hold board securely over fin, continued to fall out after rolling a few feet. Wheels were wobbly, especially on dry sand.
Tried a SUP trailer that just has a strap (instead of the bar that this trailer has) for looping over the top. Because of the curve of the fin, the strap did not hold the board from sliding. This one works great!
This may be more of a 4-star piece of equipment based on that one of the straps already broke, however given the price of the item, it can't be beat. Works well in the sand as well. We just replaced the strap that broke with a bungee cord and all is good. There are similar products that cost four times as much out there, but there is seemingly no need to spend that much. We just load the board board, strap it down and head down to the beach.
This is a very well designed, high quality product. No more sore back or bruised hip from lugging my board across beach. Easy 5 stars!
These wheels are really terrific. I have a heavy plastic SUP board and getting it down to the water was exhausting. The SUP Wheels are a breeze to use. They slide easily on the end of the board and then you can wheel your board anywhere. I have to cross uneven grass, a gravel driveway, pavements with curbs and then sand before I get my board in the water and these wheels cover all the different terrain easily. You can pull or push the board from the nose; whichever your preference.
SUP Wheels brand wheels is the best SUP transportation product on the market! I am a 105lb female and I have no problems taking my SUP board out alone. I can spend more time on my board without worrying about being too tired to bring my board back in. Oh, and my other SUP carrier got a flat the first time I used it. This SUP carrier won't go flat on me! GREAT PRODUCT!
Our inflatable SUP barely fits in it. With a little rigging, it still makes it easier to get to the beach.
