SEAWELL Inflatable Boat Launching Wheels Flipup Dinghy Wheeler Nylon Ribs Towing Wheels

I wrote a favorable review when i first received these but, six months later, I should add that the spring (which keeps the wheels locked in place) corroded quickly and broke through shorty thereafter. The large screws and nuts , around which the wheels pivot, are also rusting through. This product is not designed for a marine environment.

They worked for about 6 months of very little use. Then one of them broke rolling my 8’ dingy on the beach.
