I bought this one. Ships fairly fast even though its from China. I bought two, and each came in around a week despite Amazon telling me it would be here next month. I really like it, its nice and smooth silicone. Has quick release pins too. https://www.amazon.com/dp/B019YWFVWG/ref=cm_sw_r_other_awd_vKK6wbD66MYW5
