, these ones look good too. Using the Fifine(K678) with GatorFrameWorks Weighted Bottom Boom Arm. Note: If you like my review, please click on "Helpful". Its exactly what i wanted. Part of the comfort on concrete is probably the amount of support they give. This product is not even close -- very disappointing! This product was shipped on time and arrived as described. Así es, regresé a casa y la ropa estaba en el suelo, de la nada, sin uso rudo, sin ningún motivo, uno de los tubos se separó de la base que lo sujeta a la madera pero quebrado, no se puede arreglar. I think there awesome! For anyone like me whom apple has their hooks all in, you need this device.
