text: Very good product for the price. I gave 4 stars because it is a pain to tighten enough to keep it in place. The inside of the clamp should have some ridges so that it grips the spacers and will keep it in place better. Came from overseas and it was not mentioned online. I really did not like that. They had wrong address and it went to PA instead of MS. The shipper called me for directions and was kind enough to reroute it to me with no extra charge. It was slow to ship and it was very slow to arrive coming from overseas.
