A French press is generally pretty easy to use, but it often depends on the design. Some models will advertise a certain capacity, but they will overflow before that due to the expansion of coffee grounds as they bloom. A quality French press won’t overflow at maximum capacity. The shape of the handle and the brewer will also have a bit impact on design and use. Tall brewers can be hard to clean but wide brewers allow the coffee to cool faster. Some models have ergonomic handles while others simply get in the way, making them hard to store. The design of the spout and the lid is also critical. A broad spout will pour more quickly and be hard to control, especially when the pot is full. However, the lid can help control the pour as long as the positioning is accurate. It also needs to fit securely so you don’t have to hold it in place while you pour.
