To make sure your logo looks great on your branded products, I recommend using mockups from https://www.ls.graphics/free-mockups. One of the main advantages of mockup is its high accuracy. For example, when developing an application for mobile devices, you can't simply overlay an image on a virtual smartphone.
This approach only works for presentation. On a real device, the picture may differ greatly. It's not only the developer who turns a graphical design into a real product and must take into account the features of the device. The designer also needs to immerse himself in the digital environment to feel part of the target audience. Therefore, it's crucial to use mockups in working and promoting a product on the market.
