    Works great!

    Super light. Easy to transport two boards. Set boards in the middle and they are fairly light. I didn't have any problems with strapping them down.

    So easy to assemble!

    Wow! These products are awesome! Assembly requires no tools and I think a small child (or monkey) could handle putting it together it�s so easy! Highly recommend!

    Ease of Use

    Great product, easy to assemble and wonderful to use

    Exceeded expectations

    This double board SUP cart performs great with one or two boards. Easily holds the boards with no slipping. The wheels are extremely responsive. I push my boards with one hand on the back of the boards three blocks to the beach. I dont bother to use the to straps. The key to easy pushing is to balance the boards on the cart. Enjoy the wheels are great. One consideration is the wheels sink in sand and do not move easily.

    Game Changer!

    Now that I own this carrier I can easily access lakes with my SUPs that are further distance from the parking lot ... once you get the hang of the right weight distribution it literally seems like the boards are always traveling down hill. On my first attempt the weight distribution was incorrect and it felt like I was carrying the two boards with little help from the carrier. Second attempt went like a dream. I wouldn't say this carrier breaks down easily - and I did not attempt it. I just threw it in the back of my car (small SUV) fully assembled. Initial assembly was easy and I can see that it might break down fairly well. Love it!
