I won't mince words. The core functionality of the CROWN-CWL-300DL is a direct rip-off of the SANWA-JLFD-TP-8YT (https://focusattack.com/sanwa-jlfd-tp-8yt-detachable-joystick-lever/).
The previous quick release design, the CWL-300 DX-QR, was a direct rip-off of the Victrix Link 2. Frustratingly, my review of that item, which was sold for $39.95, is no longer available, as the store page has been deleted off of FocusAttack (https://focusattack.com/samducksa-cwl-300-series-dx-qr-quick-release-kit/). I assume that the page was deleted because the item was discontinued, which makes sense because the design was flawed.
To recap my previous review of the DX-QR, despite it being a direct rip-off of the Victrix Link 2, Crown/Samducksa failed to account for one big thing that Victrix did, which was to make special ball tops with deep/recessed sections for the shaft screw-in area to accommodate the sliding shaft. Normal ball tops, including Crown's OWN balltops, do not have this feature, so they were not compatible with the DX-QR. Only battop handles, which do typically have a wide recessed opening, were compatible with it.
With this "new" design, which again is basically functionally the same as the Sanwa, albeit with presumably altered dimensions, that issue is avoided, and all standard battop and balltop handles should work. However, that also means that the design has the same problems as Sanwa's, namely that both sides of the shaft (the side that screws into the top, and the side that screws into the base) are prone to loosening with use, and must be re-tightened periodically.
So again, without mincing words, saying that this model "takes many lessons learned from the QR" is kind of farcical. Crown/Samducksa effectively switched from one copied design to another.
The only reason I am giving this item 4 stars is because it mostly works, and because the hollow shaft cover is metal instead of Sanwa's plastic, which is a nice touch. At this point, I'm less concerned with originality than I am with companies just supporting the idea of removable levers, because that should really be standard at this point.
EDIT: Yeah, never mind. I went into this expecting to have to periodically re-tighten the top. What I did not expect was to be able to feel the thing unscrewing during every round, and hastily having to twist it back into place between basically every round. I'm not sure how this compares to the Sanwa equivalent, but I didn't expect it to be this bad. It's borderline unusable.
