This is a high quality item. I bought the SP-01 strap, and the DC-22Q unit, and I separately bought the Leofoto NP-65 plate that has the connector which pairs with the SP-01 strap. It all works really well together, and I finally have a strap with a disconnect that I like. I've had numerous other straps, and either there are no quick disconnects, or the disconnects are not good. But this Leofoto unit is very good, and I finally have a quick disconnect that I feel confident in, because I don't think the quick disconnectors will ever fail. There were other straps where I was never confident about their ability to not fail while the camera/lens combo was dangling. I liked this Leofoto unit as soon as I took it out of the box. And I applaud LeofotoUSA for their rapid shipping. Everything I've bought from LeofotoUSA has not only been very high quality, but it always arrives to me much faster than expected.
