Review on Xnrtop Coupling Diameter Aluminum Connector Power Transmission Products by Sam Pullen

Based on my experience this Collar & Universal Joiner is a total disaster. The aluminum connector failed to provide proper power transmission, causing major setbacks in our project .The only positive aspect was its affordable price, but that's not worth the trouble it caused. Unfortunately, this product tarnishes the reputation of the Couplings category. Save yourself the trouble and look for an alternative..
