I purchased 2 of these for my family. They weigh in about 45 pounds each dry, and have a nice hand-grab notch in the middle for carrying. They have 4 gear-strap screws on the front end top that bungies can be attached to, but they also loosen without warning, allowing water to enter the cavity of the board. They are styrofoam and aluminum-slat filled. When the sun hits the board from behind, I can see about 1 foot of space at the very front of the boards that are empty of any filling. I guess the foam did not completely fill it. The boards are very stable and safe for all ages, up to about 250 pounds capacity. One of my tail fins lost a screw and the fin actually fell off (they do not float). Luckily, the water was only about 2 feet deep and we found it. I have since epoxied it back into place and it is holding well. The board does flex a little, so it is about medium on the stiffness scale. The end of the board has fill hole caps where it was injection filled, then sealed. One of my boards leaks at that point, so after several hours of use, it will take on a couple gallons of water. Standing the board up after use will drain it out.
Pros
Easy to use, very durable. Great for all ages, and safe for kids. Great beginner to intermediate board. Reasonably priced.
Cons
Heavy. May take on water after several hours of use. Screws are not secure and can be lost. Tail fins can be lost.
Usage
Use mostly in local lakes around Utah. Exercise and family fun. Have even towed rider on it behind boat with ski rope.
