Very nicely made. Be prepared to solidify keeping the pieces together, as they otherwise shift a lot as you use it. I ultimately drilled through the connections underneath and placed some locking nuts. Worked great, but did require a steady drill. I first tried the suggestion from others of thick tape on the sides, but that o Lu worked for awhile. BUT, very sturdy - very pleased with the product. They should incorporate a way to lock the pieces in place though, so I deducted one star.
