Review on Velleman K8204 Upgrade Coupler Printer by Paul Tucker

Using this product, our team found that our 3D printer`s precision and stability vastly improved. The installation process was a breeze, and the new coupler significantly reduced filament slippage and thus minimizing print errors. Our prints now come out flawless with high accuracy and are much easier to manage .The only downside we found was that the product is slightly expensive compared to some similar products available on the market, but the benefits definitely outweigh the cost..
