This product is probably not of the quality the inventor intended. Half of the stud nuts are not tight enough to hold them in place. I put in washers to try and tighten it but it's still quite disappointing. I still use it occasionally, but now it's in two pieces (with the best two nuts) and I have to be very careful with it to keep the angle from shifting.
